"The magnetic field does not merely confine the plasma โ€” it is the plasma's memory. MAGNA-FLOW reads that memory and rewrites the future before the instability can." โ€” MAGNA-FLOW v1.0.0 Manifesto


Table of Contents


Overview

MAGNA-FLOW is a Physics-Informed Artificial Intelligence (PIAI) framework engineered to model, predict, and actively suppress magnetohydrodynamic (MHD) turbulence and irreversible dissipation in high-conductivity fluid media โ€” including plasma confinement systems, liquid-metal reactor cooling loops, ionic spacecraft thrusters, and astrophysical dynamo analogs.

Classical MHD solvers โ€” built on the coupled Navierโ€“Stokes and Maxwell equations โ€” become computationally intractable at real-time control timescales when magnetic Reynolds numbers exceed 10โถ and magnetic Prandtl numbers deviate far from unity: precisely the regime governing tokamak edge instabilities, Hall thruster breathing modes, and Hartmann boundary layer turbulence. MAGNA-FLOW replaces this computational wall with three cooperative neural constructs that enforce MHD physical laws as hard architectural constraints rather than soft regularization targets.

The Problem

Every unsolved challenge in real-time MHD control โ€” from suppressing plasma edge instabilities in fusion reactors to stabilizing ionic thruster plumes for deep-space missions โ€” reduces to one bottleneck: we cannot solve the coupled Navierโ€“Stokes and Maxwell equations fast enough, in the regimes that matter most, to apply meaningful control before the instability arrives. Three domains suffer acutely:

1. Tokamak Plasma Confinement (Fusion Energy) Edge-Localized Modes (ELMs) are repetitive explosive relaxation events at the plasma boundary that deposit energy fluxes exceeding 8โ€“65 MJ/mยฒ on divertor tiles in 100โ€“300 microsecond bursts โ€” far beyond the engineering tolerance of tungsten plasma-facing components. A reactor-scale tokamak (ITER) cannot reach its Q = 10 design goal if unmitigated Type-I ELMs erode the divertor on timescales of weeks rather than years. No existing real-time controller predicts ELM onset with sufficient lead time to apply magnetic perturbation mitigation before the thermal pulse arrives.

2. Hall Thruster Propulsion (Aerospace) Breathing-mode plasma oscillations in the 10โ€“30 kHz band represent the dominant source of efficiency loss and thrust noise in Hall-effect thrusters โ€” the primary propulsion technology for geostationary station-keeping and deep-space missions. Oscillation amplitude of ยฑ19.4% peak-to-peak in specific impulse translates directly to wasted propellant mass and shortened mission lifetime. No predictive AI model has demonstrated real-time breathing-mode suppression across the full operational envelope without invasive hardware modification.

3. Liquid-Metal Nuclear Cooling (Nuclear Engineering) Hartmann boundary layers in sodium-cooled and lead-bismuth-cooled fast reactor primary loops operate at Hartmann numbers up to 10โด, producing viscous layers thinner than 10 micrometers that dominate magnetoconvective heat transfer. Classical Nusselt number correlations underestimate heat transfer coefficients in the Hartmann regime by up to 25%, forcing conservative over-design of coolant flow rates and pumping power. Accurate real-time Hartmann characterization is essential for precise thermal margin management.

A unifying physical insight connects all three: every manifestation of uncontrolled MHD dynamics is an entropy production event โ€” the irreversible conversion of organized magnetic and kinetic energy into thermalized heat. MAGNA-FLOW treats ELM suppression, thruster stabilization, and Hartmann characterization as instances of a single entropy minimization problem, inheriting the Unified Dissipation State Function from ENTROPIA (E-LAB-01).


Core Constructs

1. Magnetic Fourier Neural Operator (M-FNO)

Generalizes the Fourier Neural Operator (FNO) to the full coupled MHD setting, operating simultaneously on the 6-component state vector v(r,t) = (u_x, u_y, u_z, B_x, B_y, B_z) with learnable 6ร—6 complex spectral kernels that capture the complete Alfvรฉnic coupling tensor.

  • Architecture: 8-layer FNO stack โ€” feature dimension d = 256, k_max = 64 Fourier modes per dimension
  • Input: Coupled (u, B) MHD state vector โ€” 6 components at each spatial point
  • Output: Time-evolved state v(r, t+dt) โ€” divergence-free by architectural construction
  • Captures: Alfvรฉnic wave propagation, current-sheet formation, cross-field energy cascade, reconnection precursors
  • Constraint: Helmholtz-Hodge divergence-free projection applied after every layer โ€” div(u) = div(B) = 0 is a hard guarantee, not a penalty

2. Hydromagnetic Physics-Informed Network (H-PINN)

Enforces the complete set of MHD conservation laws โ€” momentum, induction, solenoidal constraint, magnetic helicity evolution, and Onsager cross-coupling symmetry โ€” as hard loss terms evaluated at adaptive collocation points across the spatiotemporal domain.

  • Architecture: Causal collocation PINN with NTK-rebalanced multi-objective loss (4 physics terms)
  • Function: Residual correction layer applied to M-FNO output โ€” enforces helicity conservation and Onsager reciprocity
  • Constraint: dH_m/dt = โˆ’2ฮทยทโˆซ(JยทB)dV enforced as global hard constraint โ€” prevents unphysical magnetic topology drift
  • Guarantee: Onsager symmetry L_ij = L_ji enforced architecturally โ€” no spurious irreversible cross-coupling pathways

3. Lorentz Flux Resolver (L-Flux)

A model-predictive control engine that tracks the Maxwell stress tensor T_M in real time, identifies regions where its minimum eigenvalue ฮป_min approaches zero (the magnetic pressure collapse condition signaling imminent reconnection), and pre-emptively actuates external correction fields before dissipation cascades initiate.

  • Architecture: MPC solver with 500 ยตs prediction horizon โ€” warm-started from previous solution at each 50 ยตs control timestep
  • Forward model: M-FNO used internally for trajectory prediction inside the MPC loop
  • Risk map: Safety margin field ฮดฮป(r,t) = ฮป_min(T_M) โˆ’ ฮป_safe โ€” spatially resolved reconnection precursor
  • Actuation: Substrate-agnostic โ€” RMP coil currents (tokamak), magnetic lens coils (Hall thruster), external field arrays (liquid metal)
  • Latency: 1.8 ms full control cycle on A100 GPU | 87 ยตs on NVIDIA Orin (INT8 TensorRT)

Equation 3 โ€” Induction Equation (Hard Constraint)

โˆ‚B/โˆ‚t = โˆ‡ ร— (u ร— B) + ฮท ยท โˆ‡ยฒB

ฮท: magnetic diffusivity | Enforced as hard H-PINN residual term L_ind | Violation at any collocation point contributes to NTK-rebalanced training loss

Equation 4 โ€” Magnetic Helicity Evolution (Hard Constraint)

H_m = โˆซ_V (A ยท B) dV

A: magnetic vector potential (B = โˆ‡ ร— A) | J = โˆ‡ ร— B / ฮผโ‚€: current density | Enforced as global scalar hard constraint โ€” prevents topological drift across control cycles

Equation 5 โ€” Maxwell Stress Tensor

T_M^{ij} = (1/ฮผโ‚€) ยท [ B_i B_j โˆ’ (1/2) ฮด_{ij} |B|ยฒ ]

ฮผโ‚€: permeability of free space | ฮด_{ij}: Kronecker delta | L-Flux tracks ฮป_min(T_M) โ€” minimum eigenvalue collapse signals imminent reconnection

Equation 6 โ€” L-Flux Control Objective

min_{u_ctrl}  โˆซ_T โˆซ_V [ ฯƒ_Ohm(r,t) + ฯƒ_visc(r,t) ] dr dt

subject to:   ฮป_min(T_M) โ‰ฅ ฮป_safe,    |B_ctrl| โ‰ค B_max

ฯƒ_Ohm = ฮท |J|ยฒ: Ohmic dissipation rate | ฯƒ_visc = ฮฝ |e_ij|ยฒ: viscous dissipation rate | MPC solved via gradient descent warm-started from previous solution

Equation 7 โ€” MHD Entropy Production Rate

dS/dt = (1/T) ยท โˆซ_V [ ฮท |J|ยฒ + ฮฝ |e_ij|ยฒ ] dV
      = ฯƒ_Ohm_total + ฯƒ_visc_total

MAGNA-FLOW minimizes dS/dt as the direct MHD realization of the ENTROPIA Unified Dissipation State Function ฮฆ(S, J, T) โ€” thermodynamic minimum entropy production principle applied to electromagnetic fluid systems.

Equation 8 โ€” H-PINN Loss Functional

L_HPINN(ฮธ) = ฮปโ‚ ยท L_mom + ฮปโ‚‚ ยท L_ind + ฮปโ‚ƒ ยท L_div + ฮปโ‚„ ยท L_hel

Quick Start

MHD state tracking and dissipation control:

from magna_flow import MHDStateTracker
import numpy as np

# Initialize tracker for ITER-class tokamak edge plasma
tracker = MHDStateTracker(
    spatial_dim=256,
    k_max=64,
    fluid='plasma_deuterium',
    enforce_helicity=True,
    lflux_horizon_us=500       # L-Flux MPC horizon in microseconds
)

# Load pre-trained weights
tracker.load_weights('experiments/weights/mfno_pretrained_v1.0.0.pt')

# Step the MHD state forward in time
tracker.step(
    dt=1e-6,
    env_obs={
        'u_field': u_arr,      # velocity field (3 ร— Nยณ)
        'B_field': B_arr,      # magnetic field (3 ร— Nยณ)
        'T_e': T_electron      # electron temperature (scalar field)
    }
)

# Query state and risk metrics
risk_map  = tracker.get_safety_margin()     # ฮดฮป(r,t) โ€” spatially resolved reconnection risk
eta_mhd   = tracker.get_efficiency_index()  # scalar ฮท_MHD โˆˆ [0, 1]
ctrl_hist = tracker.get_control_history()   # B_ctrl time series (actuator output)

print(f"ฮท_MHD             = {eta_mhd:.4f}")
print(f"Min safety margin = {risk_map.min():.4e}")
print(f"Max dissipation   = {tracker.get_dissipation_peak():.4e} W/mยณ")

ELM suppression (full control loop):

from magna_flow import MagnaFlowEngine

engine = MagnaFlowEngine(regime='tokamak_elm', fluid='plasma_deuterium')
engine.load_weights('experiments/weights/')

# Run full ELM suppression control loop
result = engine.run_control_campaign(
    duration_ms=100.0,
    control_freq_hz=556,           # A100 GPU control update rate
    initial_state={'u': u0, 'B': B0},
    actuator='rmp_coil',
    lambda_safe=0.05               # Reconnection safety threshold
)

print(f"ELM suppression factor = {result.elm_suppression:.2f}ร—")
print(f"Mean ฮท_MHD             = {result.mean_efficiency:.4f}")
print(f"Total ฯƒ reduction      = {result.dissipation_reduction:.1%}")

Hall thruster breathing-mode control:

from magna_flow import MagnaFlowEngine

engine = MagnaFlowEngine(regime='hall_thruster', fluid='hall_xenon')
engine.load_weights('experiments/weights/')

result = engine.run_control_campaign(
    duration_ms=10.0,
    control_freq_hz=556,
    initial_state={'u': u0, 'B': B0},
    actuator='magnetic_lens',
    target_isp_stability=0.025     # ยฑ2.5% peak-to-peak Isp target
)

print(f"Isp variation (baseline)  = ยฑ{result.baseline_isp_variation:.1f}%")
print(f"Isp variation (controlled)= ยฑ{result.controlled_isp_variation:.1f}%")
print(f"Isp gain                  = +{result.isp_gain_seconds:.0f} s")

Theoretical arc: ENTROPIA (E-LAB-01) unified Boltzmann and Shannon entropy into the Unified Dissipation State Function ฮฆ(S, J, T). Each subsequent project applied this framework to progressively more complex dissipative domains โ€” from scalar thermodynamic systems (E-LAB-04), through vector-field optical systems (E-LAB-03), tensor-field thermal systems (E-LAB-07), and Riemannian metric-field spacetime (E-LAB-08) โ€” culminating in MAGNA-FLOW's extension to fully coupled vector-field electromagnetic fluid systems.
