Influence of the Angular Effect on the Heat Transfer Process in Graëtz Heat Exchanger

Lecheheb S., Bouabdallah A., Tigrine Z., Yahi F.

Abstract:
We modeled the process to establish the properties related to heat transfer involved the modified Graëtz system in MHD. Thus using a computational code based on finite volume method (Fluent CFD) sought to extend our study by generalizing the problem to angular effects when plates are no longer parallel (classical system) and become a convergent device (modified system) defined by the inclination angle a, bounded between the device plate and the axis of the flow system. The advantage of such modification will directly affect the distribution of the velocity field, temperature with or without a magnetic field effect. Under these conditions, we can expect an improvement in the transfer process by highlighting the increasing Nusselt number
