Effect of Froude Number on the Turbulent Wall Jet in Coflow Stream

Abstract

Sixth Conference on Design and Modeling of Mechanical Systems (CMSM 2015), Hammamet, TUNISIA, MAR 23-25, 2015International audienceThe influence of the coflow velocity ratio on the behavior of a non isothermal turbulent wall jet has been determined numerically. The numerical resolution of the governing equations is carried out using a finite difference method. Turbulence modeling is performed by a modified low-Reynolds number k-epsilon model. In this work, we are interested in the study of the effect of the coflow stream on the behavior of the dynamic and thermal properties of the wall jet subjected to a constant temperature. A comparison with a simple wall jet is carried out. Further, we will examine the influence of the Froude number on the wall jet emerging in a coflow stream
