Centrifugal Compressor Performance
ccp is a python library for calculation of centrifugal compressor performance. It uses CoolProp/REFPROP for the gas properties calculations.
import ccp
# ccp uses pint to handle units. Q_ is a pint quantity.
# If a pint quantity is not provided, SI units are assumed.
Q_ = ccp.Q_
ps = Q_(3, 'bar')
Ts = 300
# Define the fluid as a dictionary:
fluid = {
"CarbonDioxide": 0.8,
"Nitrogen": 0.2,
}
# Define suction and discharge states:
suc0 = ccp.State(fluid=fluid, p=ps, T=Ts)
disch0 = ccp.State(fluid=fluid, p=Q_(7.255, 'bar'), T=391.1)
disch1 = ccp.State(fluid=fluid, p=Q_(6.754, 'bar'), T=382.1)
# Create performance point(s):
point0 = ccp.Point(
suc=suc0,
disch=disch0,
speed=Q_(7941, 'RPM'),
flow_m=Q_(34203.6, 'kg/hr'),
b=0.0285,
D=0.365,
)
point1 = ccp.Point(
suc=suc0,
disch=disch1,
speed=Q_(7941, 'RPM'),
flow_m=Q_(36204.8, 'kg/hr'),
b=0.0285,
D=0.365,
)
# Create an impeller with those points:
imp = ccp.Impeller([point0, point1])
# Get results from the Impeller with methods such as
imp.head_plot()
imp.disch.T_plot()
