Abstract

Impacts jets are widely used in industry whose purpose is the thermal transfer of industrial objects or thermal comfort of premises. This work is devoted to the numerical study of the influence of the variation of the impact distance on the thermal and dynamic behavior of a swirling jet impacting a plane plate. The variables treated are the reduced velocity Ur the reduced temperature Tr and the number of Nusselt Nu. In order to concretize our study, we made the numerical simulation based on the method of the finite volumes by means of the mathematical model with two equations of transport (k-ɛ) for the closure of the equations of NAVIER-STOCKES and this, by using the code of FLUENT calculation for the numerical resolution of such a flow. The results found clearly show the influence of this factor on the thermal and dynamic characteristics of the impact jet. The (k-ɛ) model gave acceptable and confrontational results with available experimental results.
