The Effect of Variable Thermal Conductivity in Thermal-Hydraulic Calculations

Nuclear Technology, 1976
Many thermal-hydraulic computer codes employ a fuel rod heat transfer model to couple the fuel rod temperatures with the hydraulic driving forces.

On a New Turbulent Energy Equation With Variable Thermal Conductivity

Volume 10: Heat Transfer, Fluid Flows, and Thermal Systems, Parts A, B, and C, 2008
The present work investigates the energy equation of a general fluid, Newtonian or non-Newtonian, with variable thermal conductivity in turbulent flow. The usual energy equation, without the dissipation terms, is taken into account with the fluctuating terms in the temperature as well as in the thermal conductivity.

TRANSIENT CONDUCTION AND RADIATION HEAT TRANSFER WITH VARIABLE THERMAL CONDUCTIVITY

Numerical Heat Transfer, Part A: Applications, 2002
The effect of variable thermal conductivity on transient conduction and radiation heat transfer in a planar medium is investigated. Thermal conductivity of the medium is assumed to vary linearly with temperature, while the other thermophysical properties and the optical properties are assumed constant.

MHD Convection of an Electrically Conductive Fluid with Variable Thermal Conductivity

Applied Mechanics and Materials, 2011
The effect of temperature-dependent thermal conductivity on the magneto-convection in a low Prandtl number liquid is investigated numerically. The liquid is contained in a closed square cavity with isothermal vertical walls kept at different temperatures. The top and bottom walls are assumed to be insulated.

Variable Thermal Conductivity and Perforation Effects on a Heat-Conducting Plate

Journal of Thermophysics and Heat Transfer, 2010
T HE heat transfer across irregular surfaces, such as perforated plates, has been extensively studied in the past to control the rate of thermal energy in heat exchanger devices. In some cases the use of perforated plates within ranges of temperature at which the material that constitutes the plate exhibits a temperature-dependent thermal conductivity ...

Steady-State Conduction With Variable Thermal Conductivity

Journal of Heat Transfer, 1962
A method is developed for solving two-dimensional, steady-state heat-transfer problems with thermal conductivity dependent on temperature. The quantity ∫ KdT is employed in the analysis and although this quantity has been known for some time,2, 3 it seems that the real usefulness of this quantity in analysis has not been, in general, recognized.

Variable Conductance Heat Pipe for a Lunar Variable Thermal Link

41st International Conference on Environmental Systems, 2011
The Anchor Node Mission for the International Lunar Network (ILN) has a Warm Electronics Box (WEB) and a battery, both of which must be maintained in a fairly narrow temperature range using a variable thermal conductance link. During the lunar day, heat must be transferred from the WEB to a radiator as efficiently as possible.

Transient Conduction in a Hollow Cylinder With Variable Thermal Conductivity

Journal of Heat Transfer, 2010
A closed form approximate solution has been obtained for the transient temperature distribution in a hollow cylinder with a linear variation in thermal conductivity with temperature. The boundary conditions considered are convective heating (Newton’s law) at the exposed inner surface and adiabatic outer surface.

Variable Thermal Conductance Metamaterials for Passive or Active Thermal Management

Volume 1: Development and Characterization of Multifunctional Materials; Mechanics and Behavior of Active Materials; Bioinspired Smart Materials and Systems; Energy Harvesting; Emerging Technologies, 2017
To continue to meet spacecraft systems ever increasing thermal management requirements, new control methods need to be developed. While advances in metamaterials have provided the ability to generate materials with a broad range of material properties, relatively little advancement has been made in the development of adaptive metamaterials.
