Abstract

In this paper, the turbulent flow in an asymmetric two-dimensional diffuser is investigated. In many applications, it is important to know whether the boundary layer (laminar or turbulent by calculating the Reynolds number, which is the ratio of the inertia force to the viscous fluid flow force) will separate from the surface or inside a particular body. If this happens, it is also important to know exactly where the flow separation will occur. The separation can be internal or external. This is quite important in many tasks.
