Enthalpy equation in code_saturne
Posted: Wed May 31, 2023 4:56 pm
Hi,
I am Running 2D convergence nozzle with Enthalpy equation in version 7.1.2. the area ratio is 4 so the pressure and velocity change along x direction is significant.
The Enthalpy equation described in theory guide page 17 is as follows: here dp/dt is the lagrangian derivative of pressure.
Since pressure and velocities are changing I should expect change in Enthalpy (should be decreasing ) but I see not change at all.
I have attached the setup and subroutines I am using.
