 February 15, 2006, 22:25 Re: laminar simulation #3 Rajesh Guest   Posts: n/a It depends on your problem. For example, if it is pipe flow (with a sharp-edged entrance), the laminar-turbulent transition takes place at approx. Re(-based on diameter of pipe) of 2300(Lower limit), and for a flat plate, Re(-based on distance from the leading edge) is around 3.2x10^5(lower limit)for transition. Regards, Rajesh

Regards Emanuele
