Algerian Journal of Engineering Research


Description

The Algerian Journal of Engineering Research The Algerian Journal of Engineering research is an English language peer–reviewed halfyearly publication of original research and reviews articles dealing with fundamental and applied research and innovation in the field of Engineering and related areas. Thus theoretical, interpretative or experiment high quality papers are welcomed. The Algerian Journal of Engineering research is issued and published by Salah Boubnider University of Constantine in collaboration with a local and is edited by a local and an international group of eminent researchers. Papers previously published elsewhere cannot be accepted for the journal. The acceptance for publication lies with the editors and is based on the recommendations of at least two ad hoc referees, and of the editorial board, if necessary

Effect of the impact distance on the thermal and dynamic behavior of a swirling jet impacting a flat plate

زروت عمر,  Khelil Ali, 

Résumé: 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.
