Dear all,
I am doing FD fan simulation in Ansys CFX. I gave boundary conditions total pressure inlet and mass flow rate outlet. I have two doubts in giving the above boundary condition
1. Suction pressure which is given as inlet condition will be either same for all mass flow derived or it will be different for each condition. By increasing mass flow, the suction pressure will be changed or not for same speed of impeller...
2. Whatever suction pressure(just like atmospheric condition total pressure=0 instead of giving suction pressure value) is given based on that the pressure difference will be adjusted itself. Is it right?
Thank you in advance.
