1.	The turbulent kinetic energy production is limited to prevent the build-up of turbulence in __________ regions.(a) far-field(b) near-wall(c) stagnation(d) trailingI got this question in a national level competition.My question comes from Turbulence Modelling topic in chapter Turbulence Modelling of Computational Fluid Dynamics
Answer» The correct choice is (C) stagnation For EXPLANATION I would say: In the stagnation region, the VELOCITIES will be zero. So, there is no possibility of TURBULENCE there. The MODEL should be limited to prevent unrealistic turbulence in the stagnation region.
