Hi guys,


I am trying to simulate flow over a heated equilateral triangle at Re 500 in fluent.
Is using laminar unsteady model for this study correct?

It is quite difficult to say if such geometry generates large turbulence in the separation region. Try a laminar setting using a 2D geometry and then check the same solution in a 3D gemoetry, for example using periodic conditions in the spanwise direction. Compare the solution to first assess if 3D effects are relevant or not.
