Forced convection along a wall. Liquid metals application
Description
From the experimental results in pipes, heated with constant wall heat flux, the dynamical and thermal structure of the wall region of a turbulent flow is studied. We can show that, for high values of Reynolds and Peclet numbers, logarithmic profiles of velocity and temperature exist. A continuous description of the wall is obtained with the use of simple modelisation. The study of the thermal wall region structure is then made in the case of a liquid metal flow

A partir des resultats experimentaux obtenus en conduite chauffee a flux constant, la structure de la zone d'un ecoulement turbulent controlee par une paroi est etudiee au point de vue hydrodynamique et au point de vue thermique. Nous pouvons alors demontrer qu'il existe, si les nombres de Reynolds et de Peclet sont assez grands, des lois logarithmiques de vitesse et de temperature. A l'aide de modeles simples, on peut obtenir une description continue de la zone controlee par la paroi. Enfin, l'etude de la zone de paroi est reprise, au point de vue thermique, pour les metaux liquidesFiles
