On conjugated problems of heat transfer

International Journal of Heat and Mass Transfer, 1961
Abstract The paper deals with the simplest “conjugated” boundary value problems of heat transfer in which heat conduction equations are solved in common for a body with heat sources and for a liquid flowing round the body. The method of the asymptotic solution of integral equations occurring in conjugated problems is presented.

CONJUGATE HEAT TRANSFER IN POROUS ANNULUS

Journal of Porous Media, 2014
The effect of conductivity ratio on temperature at a solid-porous interface is one of the most important aspects in conjugate heat transfer. The present work is undertaken to investigate heat transfer behavior in a porous annular vertical cylinder having a solid wall at the inner surface The main objective ofthe present study is to evaluate the effect ...

Modeling conjugate heat transfer

2010 3rd International Conference on Thermal Issues in Emerging Technologies Theory and Applications, 2010
Modeling conduction heat transfer in electronic systems has gained some maturity over the past 3 decades. Although new modeling challenges were associated with 3D stacked dies or packages, some modeling approaches were proposed to handle this rather complicated multiple heat source problem.

The conjugate heat transfer of the partially heated microchannels

Heat and Mass Transfer, 2007
In this paper, the conjugate heat transfer of the water flow inside the microtube (D i/D o = 0.1/03 and 0.1/0.5 mm) was investigated. The laminar regime was considered with Re up to 200, input heat transfer rate of Q 0 = 0.1 W and variable thermophysical properties of the water ...

Unified Solution of Conjugate Fluid and Solid Heat Transfer – Part II. High-Order Conjugate Heat Transfer

Advances in Applied Mathematics and Mechanics
Summary: A high-order unified solution method is presented for simulating the coupled fluid flow and heat transfer phenomena in solid materials. The method integrates the energy transfer processes of fluid and solid by transforming the compressible Navier-Stokes equations into a dimensionless system through a double-time-scale approach.

Conjugate heat transfer in square enclosures

Heat and Mass Transfer, 2006
Building elements represented by square vertical enclosures encircled with finite walls or with centered solid body, could maintain the equivalent fluid volumes through the volume ratio scale. Present work aims to investigate the fluid flow and heat transfer in these two building elements.

Conjugated Heat Transfer in Heat Spreaders With Micro-Channels

Volume 3: Gas Turbine Heat Transfer; Transport Phenomena in Materials Processing and Manufacturing; Heat Transfer in Electronic Equipment; Symposium in Honor of Professor Richard Goldstein; Symposium in Honor of Prof. Spalding; Symposium in Honor of Prof. Arthur E. Bergles, 2013
This work is aimed at the experimental verification of a recently proposed single domain formulation of conjugated conduction-convection heat transfer problems, which are often of relevance in thermal micro-systems analysis. The single domain formulation simultaneously models the heat transfer phenomena at both the fluid streams and the channels walls ...

Conjugate convective heat transfer problems

International Journal of Heat and Mass Transfer, 1974
Abstract From the analysis of a conjugate problem of convective heat transfer in a laminar incompressible flow around a flat plate of a finite thickness the design formulas are suggested for a local Nusselt number Nux(Nux/Nux0)−1 = CBx ...

CONJUGATE HEAT TRANSFER OF A FINNED TUBE PART A: HEAT TRANSFER BEHAVIOR AND OCCURRENCE OF HEAT TRANSFER REVERSAL

Numerical Heat Transfer, Part A: Applications, 1995
The conjugate heat transfer in a high-performance finned-lube heat exchanger element was calculated for three-dimensional thermally and hydrodynamically developing laminar flows. The influence of Reynolds number Re and a fin efficiency parameter Fi (ratio of fin to fluid conductivity times fin thickness to fin pitch) on the heat transfer behavior has ...

Konjugierter Wärmeübergang (conjugate heat transfer)

2000
Es handelt sich um Warmeubergangssituationen zwischen einer festen Wand und dem angrenzenden Fluid, bei denen die thermischen Randbedingungen an der Grenzflache zwischen beiden Systemen nicht a priori festliegen.
