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, 2006Building 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, 2013This 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 ...

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 ...

Conjugate convective heat transfer problems
International Journal of Heat and Mass Transfer, 1974Abstract 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 unsteady heat transfer simulation in a turbine stage
36th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 2000A 3-D, unsteady, conjugate heat transfer Navier-Stokes solver has been used to simulate flow and heat transfer in a turbine. Simulations were performed for a singlestage turbine in the presence of a combustor hot streak. Time-average mid-span surface pressures were compared with experimental data.

An Immersed Boundary Method for Conjugate Heat Transfer Problems
ASME 2010 3rd Joint US-European Fluids Engineering Summer Meeting: Volume 1, Symposia – Parts A, B, and C, 2010This paper provides an immersed boundary method using a flexible local grid refinement technique for solving conjugate-heat-transfer problems. The proposed method is used to solve the flow past a heated hollow cylinder inside a channel together with the temperature field within the cylinder and then to predict turbomachinery blade cooling.

Uncertainty Quantification and Conjugate Heat Transfer: A Stochastic Analysis
Volume 4: Heat Transfer, Parts A and B, 2012Conjugate Heat Transfer studies are a common method to predict the thermal loading in high pressure nozzles. Despite the accuracy of nowadays tools, it is not clear how to include the uncertainties associated to the turbulence level, the temperature distribution or the thermal barrier coating thickness in the numerical simulations. All these parameters
