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.

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.

Local forced convective heat transfer from protruding and flush-mounted two-dimensional discrete heat sources

International Journal of Heat and Mass Transfer, 1990
Abstract Experiments are undertaken to measure the local forced convective heat transfer characteristics of an array of two-dimensional discrete heat sources. Air flow rates yielding effective channel Reynolds numbers in the range from 1000 to 10000 are employed. Flush-mounted and protruding heater configurations are investigated in the study.

Experimental and Numerical Investigation of Mixed-Convection Heat Transfer from Protruding Heat Sources in an Enclosure

Experimental Heat Transfer, 2012
Heat transfer from a 5-by-4 array of protruding heat sources in the bottom wall of an adiabatic enclosure is investigated experimentally and numerically. The enclosure has a fixed inlet and different outlets. Flow velocity and applied heat fluxes are varied. Steady-state temperatures of the heat sources, air inlet and outlet temperatures, and enclosure

Mixed convection air cooling of protruding heat sources mounted in a horizontal channel

International Communications in Heat and Mass Transfer, 2009
Abstract A numerical study of laminar mixed-convection heat transfer to air from two identical protruding heat sources, which simulate electronic components, located in a two-dimensional horizontal channel, is presented in this paper. The finite volume method and the SIMPLER algorithm are used to solve the conservation equations of mass, momentum ...
