A Modeling Study of Microscale Convection on the Heat Transfer Mode of a Fluid

Abstract

This paper deals with microscale convection on the heat transfer mode associated with the bulk movement of a fluid. It occurs when a fluid is in contact with a solid surface, and when there is a temperature difference between the surface and the fluid. Whether the motion of the fluid particles is due to density differences imposed by a temperature distribution in the fluid and the resultant buoyancy device, as in the case of face and natural convection, or due to an external device such as a pump that forces the fluid pass the surface, the energy transport phenomenon in convection in always closely related to the fluid motion. Thus, the analysis of convective heat transfer involves a careful analysis of the fluid flow, its behaviour, and characteristics.
