Hi All,
I performed a simulation by using rhoPimpleFoam about an inviscid, laminar flow in a 2D de Laval nozzle (walls are adiabatic). Mesh and results (compared to isentropic calculation) are attached. Mach and pressure profiles along nozzle are correct,but temperature is not! It seems that temperature increases along the cylinder before the nozzle inlet, then it assumes the correct trend inside the nozzle. It looks like T (and rho) is decoupled from the other quantities (p and U). Could anyone help me? Thanks. Tommy |
