Thermal boundary layer in liquid metals with variable thermal conductivity

Flow, Turbulence and Combustion, 1978
This paper deals with the analysis of the steady state laminar thermal boundary layer in liquid metals with variable thermal conductivity. For a general class of inviscid flows specified by the power law distribution, explicit closed form analytical solutions are given for temperature distributions using regular perturbation technique and they are ...

Thermal conduction of a circular inclusion with variable interface parameter

International Journal of Solids and Structures, 2001
Abstract An imperfect bonding problem associated with a solitary circular inclusion embedded in an infinite matrix under a remotely applied uniform intensity is considered. Specifically, we study the effect of imperfect interfaces which are either of weakly or of highly conducting type and that the interface parameter could vary arbitrarily along ...

Transient heat conduction in a composite slab with variable thermal conductivity

International Journal for Numerical Methods in Engineering, 1979
AbstractTransient heat conduction in a composite slab is investigated in the present work by using the orthogonal collocation method. The present numerical method is found to be quite efficient and highly stable even for the power‐type temperature dependence of thermal conductivity which often cuases severe computational instability to many numerical ...

Variable Thermal Conductivity Metamaterials Applied to Passive Thermal Control of Satellites

Journal of Thermal Science and Engineering Applications, 2023
Abstract Active materials like the proposed variable thermal conductivity metamaterial enable new thermal designs and low-cost, low-power, passive thermal control. Thermal control of satellites conventionally requires active thermal control systems that are expensive, large, inefficient, energy-intensive, and unavailable for CubeSats ...

Heat distribution in a plane with a crack with a variable coefficient of thermal conductivity

Asymptotic Analysis, 2016
We prove the existence of a solution to a problem modeling the stationary heat distribution in an inhomogeneous plane with a crack and derive explicit representations of singular terms of an asymptotic expansion of the heat flow in the vicinity of the crack tips.

The influence of variable viscosity on delayed cooling due to variable thermal conductivity

Physics of the Earth and Planetary Interiors, 2004
Abstract Recently it was found for constant viscosity models that variable thermal conductivity can delay significantly the secular cooling of the mantle. We have verified that this same effect also holds up well for variable viscosity, in which we have used up to a factor of 3000 in the lateral viscosity variations due to temperature and a factor of

Variable thermal properties and thermal relaxation time in hyperbolic heat conduction

27th Aerospace Sciences Meeting, 1989
Numerical solutions were obtained for a finite slab with an applied surface heat flux at one boundary using both the hyperbolic (MacCormack's method) and parabolic (Crank-Nicolson method) heat conduction equations. The effects on the temperature distributions of varying density, specific heat, and thermal relaxation time were calculated.
