 June 7, 2004, 14:09 swirl flow #1 rvndr Guest   Posts: n/a hi friends how to model a swirl flow.....in a 2D combustor with velocity inlet and pressure outlet as a boundary conditions.I tried by selecting define---models---solvers----axisymmetric swirl flow. Is this is the correct way. if this is the correct way then how to calculate 1.Axial component of flow direction 2.Radial component of flow direction. I know only inlet air velocity and swirl number for example (velocity 1m/sec and swirl number 0.3). Ofcourse mass flow also I know. If there is any literature plz do help me Thanks in advance regards rvndr

Hey Im new to CFD, and im simulating combustion chamber of a gas turbine. Im using 2D axisymmetric. I have mention the swirl number and inlet velocity. How do I calculate the swirl velocity??? Please help. Im new to this. Any help will be appreciated. Please.
