Utilisation de fonctions objectifs locales pour l'optimisation topologique deséchanges thermiques d'un canal vertical asymétriquement chauffé

Abstract : In the context of the topological optimization of a vertical channel asymmetrically heated inmixed convection, a new local cost function is defined and studied. This local cost function involvessome physical quantities in each point of the computational domain, namely the angle between thevelocity vector and the gradient of temperature in order to increase the heat transfer in the channel. Anumerical experiment is carried out along with the use of some more classical global cost functions. Achannel shape with increased heat convection is obtained.
