WebSTAGNATION FLOW ON THE SURFACE OF A QUIESCENT FLUID- AN EXACT SOLUTION OF THE NAVIER-STOKES EQUATIONS* By C. Y. WANG Michigan State University Abstract. A lighter fluid impinges downward on a heavier, otherwise quiescent fluid. The region near the stagnation point is investigated. WebIn this paper, a method where a dynamic equation of intermittency combining with a two-equation k-c0 turbulence model is described. This intermittency factor is a premultiplicator of the turbulent viscosity computed by the turbulence model. Following a suggestion by Menter et alJ 11,the start of transition is computed based on local variables.
