Improvment of Free Convection Heat Transfer Rateof Rectangular Heatsink on Vertical Base Plates

Improving the natural convective heat transfer of a rectangular heatsink using superhydrophobic walls: A numerical approach

The effect of utilizing superhydrophobic walls on improving the convective heat transfer in a rectangular heatsink has been studied numerically in this paper. The vertical walls were kept at isothermal hot-and-cold temperatures and horizontal walls were insulated. The boundary condition on the walls was: no-slip for regular, and slip (with slip length of 500 µm) for superhydrophobic walls. By c...

Heat transfer correlations for free convection from upward-facing horizontal rectangular surfaces

A critical review of the heat transfer data available in the literature for free convection from upwardfacing heated rectangular plates is conducted. The review is organized in the form of a table, so as to give the reader the opportunity to compare the dimensionless correlating equations presented, and the conditions under which the heat transfer data were obtained. A comparative survey of the...

Natural convection heat transfer in an oscillating vertical cylinder

This paper studies the heat transfer analysis caused due to free convection in a vertically oscillating cylinder. Exact solutions are determined by applying the Laplace and finite Hankel transforms. Expressions for temperature distribution and velocity field corresponding to cosine and sine oscillations are obtained. The solutions that have been obtained for velocity are presented in the forms ...

Unsteady free convection flow between two vertical plates with variable temperature and mass diffusion

The unsteady free convection flow between two long vertical parallel plates withvariable temperature and mass diffusion in the presence of the thermal radiation hasbeen presented. The governing dimensionless coupled linear partial differentialequations on the flow are solved by using the Laplace transform technique. TheExact solutions have been obtained for the fluid velocity, temperature and t...
