Abstract

In this paper, we are interested on the study of the turbulent flow inside a waste heat recovery system with a 25° inclined diffuser. For thus, we have developed a numerical simulation using a CFD code. Particularly, we are interested to visualize the temperature, the velocity, the total pressure, the dynamic pressure, the vorticity, the turbulent kinetic energy, the turbulent dissipation rate and the turbulent viscosity. The numerical model is based on the resolution of the Navier-Stokes equations in conjunction with the standard k-ε turbulence model. These equations were solved by a finite volume discretization method.
