hi I want to model a water pump for auto apps. using star-cd. Can tell me how i may go about this. I guess I would need a rotating mesh or rotating reference plane. Also I believe it is a steady state calc.
Any ideas, also any references on the subject will be appreciated.
Re: water pumps
You can use the implicit multiple reference frame capabilities of STAR. You will need to specify a volume of fluid which is "swept" by the impeller blades of the pump. You need to model the blades using this approach. You will also need to define a local cylindrical coordinate system, with the z-axis coinciding with the axis or rotation of the pump. The rotational speed of the pump in (rpm) also needs to be specified.
The "swept" volume will be solved in a rotating frame. The inlet scroll and exit volumes will be solved in a stationary frame. The calculation is steady state.
