Web1 de jan. de 2003 · Similar to the smooth case, k is overestimated around the hillcrest by the standard k–ε, and this fault is corrected by the two revised k–ε models. As will be discussed later in detail in Section 3.2.3 , it is clearly observed that change in position of the separation point leads to the change in reattachment length (smooth and rough cases). WebKeywords : stagnation point flow, non-Newtonian fluid, heat transfer, suction, numerical solution Introduction 1The two-dimensional flow of a fluid near a stagnation point is a classical problem in fluid mechanics.
