Head loss in sudden expansion: how evaluate it numerically

MFN · May 26, 2018, 12:31

Hello,

I'am stuck, i a need to evaluate the head loss due to a sudden expansion.
The main problem is : i can't neglige the regular head loss...
So, how can i evalute only the head loss due to the sudden expansion?

The final goal is to compare the result between CFD solution and correlation.

P.S: I apologize if i posted in the wrong forum.

Thanks,

You can simply compare the total pressure difference before and after the contraction.

Thanks
