Hello.

I'm a student of Mechanical Engineering and I'm trying to project a PEM cell.

Now, I'm studing the influence of different profiles into pressure loss.

THE SOFTWARE IS COSMOS FLOWORKS

For now, let's focus in a common serpentine.

I have working pressure and inlet volume flow rate.

I put as bondary conditions, the inlet volume flow in the inner face of inlet cavity and at the outlet cavity, I put static pressure and pressed 'OK'.

As inicial conditions, I put the inlet face and accepted the entries. P and T default, defined previous at Wizard.

I choose, than, Static Pressure at inlet and outlet surface. And Global Goals velocity and density.

I run the solver.

Next I put everything in Floworks calculator.

I want to know if I can trust in this way of getting pressure loss... Am I right?


I believe that it will give me the inlet pressure that I need to choose a pump.

Sorry for my english and for the big text... but I'm trying to learn the software by myself.

Thanks for everyone...

Rodrigo.
