Abstract
In this work, we present a numerical study of mixed convection heat exchange in a
cubic cavity of a laminar three-dimensional (3D) incompressible flow. This study
predicted the behavior of the flow structure between Multi clear structure dominated
by natural convection when the Reynolds number is small, and a Multi clear structure
dominated by forced convection when the Reynolds number is high. First, we fix the
Grashof number for the variable Reynolds number. Second, we vary the number of
Grashof for which the Reynolds number is kept fixed. The results obtained give a clear
comparison with those found in the literature it examines and explains the thermal
and dynamic characteristics of the flow.
