OPTIMAL PERTURBATION FOR MIXED CONVECTION HEAT TRANSFER IN RECTANGULAR CHANNEL
Journal Title: TEHNOMUS - Year 2011, Vol 18, Issue 1
Abstract
We studied the growth velocity perturbation at the entrance of a rectangular channel for mixed convection heat transfer. The flow is bidimensionnel and the fluid is newtonian, incompressible obeying to Boussinesq approximations. Particular forms of entry velocity profile allowing a better heat transfer inside a channel for a given regime of flow is determined. Optimal control method based on adjoint equations is used to obtain optimality condition.
