Modélisation des échanges par convection dans un canal rectangulaire muni d’ailettes.

Abstract

The objective of this study, consists in establishing an empirical model calculation of the coefficient of thermal exchange by convection, during the air flow in a rectangular conduit, whose lower plan is provided with baffles of rectangular forms laid out in quincunx. By the method of the dimensional analysis, one could connect all the physical, thermophysical parameters and the geometrical characteristics of the baffles, and according to the mode of flow one estimates a coefficient of exchange by convection in the space of flow of the fluid
