While conditions at boundaries may be steady, shear action near walls and other velocity profiles lead to time-dependent pressure and velocity fluctuations transported by and affecting the mean path of the fluid.

As a result, computational demands for exact solutions of industrial turbulent flows far exceed available computing resources.<\/p>\n<p>In\u00a0<span class=\"keyword\">Discovery<\/span>, the k-omega SST turbulence model is appropriate for most cases and is the default for both time-dependent and steady-state simulations.
