STUDY OF COMBINED HEAT TRANSFER IN A THREE-DIMENSIONAL ENCLOSURE WITH A PROTRUDING HEAT SOURCE

Numerical Heat Transfer, Part A: Applications, 1997
An experimental and numerical study of three-dimensional natural convection-radiation conjugate heat transfer in an enclosure adjacent to a heat-generating chip has been performed. A three-dimensional simulation model is developed by considering heat transfer phenomena by conduction, convection, and radiation.

CONJUGATE NATURAL CONVECTION FROM AN ARRAY OF PROTRUDING HEAT SOURCES

Numerical Heat Transfer, Part A: Applications, 1996
Abstract Coupled conduction and natural convection heat transfer has been investigated numerically for protruding heat sources mounted to one vertical wall of a rectangular cavity. The heat sources simulate an array of computer chips mounted on a substrate of finite thermal conductivity.

Mixed convection heat transfer from a horizontal channel with protruding heat sources

Heat and Mass Transfer, 2004
A numerical investigation is carried out to study fluid flow and heat transfer characteristics of conjugate mixed convection from a two dimensional horizontal channel with four protruding heat sources mounted on one of the finite thick channel walls. The flow is assumed as laminar, hydrodynamically and thermally developing.

The Aspect Ratio Effect on Natural Convection in an Enclosure With Protruding Heat Sources

Journal of Heat Transfer, 1991
The aspect ratio effect on natural convection heat transfer in a rectangular enclosure with protruding heat sources has been experimentally investigated. Five protruding heaters were mounted with uniform vertical spacing on one vertical wall. The vertical wall opposite to the wall on which heated sections were mounted was movable so that the enclosure ...

Computations of liquid immersion cooling for a protruding heat source in a cubical enclosure

International Journal of Heat and Mass Transfer, 1993
Abstract Three-dimensional natural convection flow and heat transfer were studied numerically for a heated, protruding substrate-mounted chip or package in a cubic enclosure filled with a dielectric liquid. The governing steady-state equations for the natural convection within the liquid and the conjugate conduction within the element and the ...

Lattice Boltzmann Computations of Natural Convection Heat Transfer of Nanofluid in a Square Cavity Heated by Protruding Heat Source

Journal of Thermal Science and Engineering Applications, 2020
AbstractThis paper reported the mathematical modeling and numerical simulation of natural convection flow of Cu/water nanofluid in a square enclosure using the lattice Boltzmann method (LBM). The cavity is heated from below by heat source and cooled by the top wall. The vertical walls are adiabatic.

Heat transfer enhancement from protruding heat sources using perforated zone between the heat sources

Applied Thermal Engineering, 2009
Abstract This study is to experimentally investigate the heat transfer enhancement by perforation in air cooling of two in-line rectangular heat sources module. Two separation distances between the heat sources were investigated at s/L = 0.5 and 1.0. The area between the heat sources in both cases were perforated in aligned arrangement such that the ...
