I have to model jet flow with a mach between 0.325 - 1.054. I am not sure whether to use the pressure based or density based solver .
Additionally I have been given exhaust velocity and temperature ( which can be specified in velocity inlet ) but also gamma equivalent, total pressure and total temperature values. I am not sure on where to specify these values, any help will be greatly appreciated. |

Why not run a simulation with each solver and see how the results differ.

pressure based solver is ok for these low machs and it has more features than density based solver. go for pressure solver

Here you are (below) when to use each solver and examples to use in case studies
