March 27, 2013, 08:55	Prism Layer (Boundary Layer) Thickness	#1
Peter-27 New Member Peter Join Date: Mar 2013 Posts: 1 Rep Power: 0	Hi, i'm using the Star-CCM+ software to model a vehicle and a little confused about the prism layer thickness. I know that the prism layer is to model the boundary layer, but the equation for boundary layer contains the Reynolds number. The Reynolds number changes at each point along the length of the car which will mean that the boundary layer will change. Therefore, what should my prism layer thickness be as prism layer thickness can't change along the length of the car .. Thanks in advance, Peter.
