Head (m) as in put parametrer
How to input head (m) as a input parameter??? I have tried using this constant mass flow rate in different guide vane angles but the result of head head varies from 750 m to 12 m which in my veiw no possible.
My script is LIBRARY: CEL: EXPRESSIONS: Accumulated Time Step = 100 Angular Velocity = 529 [rev min^-1] Current Time Step = 100 H net = Hin -Hout Head = Total Pressure in Stn Frame/gama Hin = massFlowAve(Head )@Inlet Hout = massFlowAve(Head )@Outlet Hydraulic power = gama *Q *H net Q = massFlow()@Inlet /massFlowAve(Density)@Inlet Reference Pressure = 1 [atm] Sequence Step = 100 Time = 0 [s] atstep = Accumulated Time Step ctstep = Current Time Step efficiency = (shaft power /Hydraulic power )*100 gama = 9806 [N*m^-3] omega = Angular Velocity shaft power = (torque_x()@Rotating Default )*(omega*2*pi/(360[degree])) sstep = Sequence Step t = Time END END END Please help me with this matter |
WHy not just define the inlet as a total pressure boundary and the outlet as a pressure boundary? Then you simply define the pressure loss over the system. Read the documentation section on "Choice of boundary conditions" for further details.
