We are carrying out analysis ( flow simulation) for a pump. We wanted to obtain the pump characteristic curve for the model.
We gave the following inputs for trails :
a. Input volume flow rate ( m3/s).
b. static pressure at outlet.
Besides, we tried environmental pressure at the outlet instead of static pressure.
On both these cases, we found that the pump curve, particularly head is climbing up against the discharge Q.
Any suggestions? What should be the ideal boundary conditions or the factors that should be given as input to achieve required output.
Thank you for your valuable suggestions.
