Modèles empiriques de calcul des pertes de charge dans un conduit rectangulaire muni de rugosités artificielles – Cas des insolateurs à air

Abstract

The purpose of this work is to find empirical models connecting losses burden to the geometric characteristics of artificial roughness said baffles and different modes of provisions of these fluid in the vein of a rectangular channel. An experimental device was developed to measure the burden of losses caused by squabbles between the upstream and downstream of the channel. The experimental measurements made have allowed us to establish empirical relationships to estimate losses due to load a configuration and arrangement of baffles and for different flow regime.
