On the k-e stagnation point anomaly
WebSince the flow cannot pass through the plate, the fluid must come to rest at the point where it meets the plate. In other words, it ``stagnates.'' The fluid along the dividing, or ``stagnation streamline'' slows down and eventually comes to rest without deflection at the stagnation point. Bernoulli's equation along the stagnation streamline gives WebThe equations of motion, in usual notation, for steady stagnation-point flow using the boundary layer approximations are. (3.56) (3.57) where u, υ are the velocity components in the x and y directions, respectively, ν is the kinematic viscosity of the fluid, U = U ( x) = ax is the straining velocity of the stagnation-point flow, and a is a ...

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.
