A Simple Question

Thomas P. Abraham

Hello Everyone:

I have a question for you all. The fluid is incompressible. Both the flow and the energy equations are solved. The standard approach is to apply velocity at the inlet and a constant static pressure at the outlet. We get the static pressure at the inlet as part of the solution.

Now, to my question. Does the actual value of static pressure at the outlet effect the solution? Let's say the static pressure at the inlet is Pinlet and the static pressure at the outlet is Poutlet. I would think (Pinlet - Poutlet) would be the same independent of the value of Poutlet. Since temperature depends on the absolute value of static pressure, I would think that actual value of Poutlet effects the thermal field. I will be trying this out soon and let you all know.

In the meantime, all your feedbacks are welcome and appreciated.

Special note to John: You are most welcome to add your philosophical view points because I really enjoy reading all that.

Thanks,

Thomas
