external convective or radiant heat flows of high density act (see Fig. i) has a number of …

Determination of the heat transfer coefficients in porous media Page 1 Journal of Engineering
Physics and Thermophysics, VoL 65, No. 6, 1993 DETERMINATION OF THE HEAT TRANSFER …

The study is about the thermal control of porous walls submitted to severe heat fluxes. The
numerical approach model of heat transfer, developed, is based on energy balance …

Equations are developed to describe the thermal exchange when a coolant is forced
through a heated porous wall, and solutions are obtained on the basis of a simplified model …

A simple analysis is described addressing the effect of simultaneous cooling from the back
side and from a transpiration flow through a porous wall. The analysis draws from existing …

An analytical investigation of the performance of a heat exchanger containing a conductive
porous media was made. The partial differential equations governing the steady-state …

Effusion cooling consists in forcing a gas under pressure through a porous material thereby
absorbing heat from the material and forming a heat insulating layer on the exposed surface …

The rate of heat transfer between a fluid stream in turbulent flow and a smooth, solid wall is
largely controlled by the relatively high resistance of the laminar sublayer next to the wall …

A limiting case of solid-fluid heat transfer is examined, in which a gas passes through a
porous wall of high specific surface with heat generation within the solid material …

Studies of the stationary heat transfer and effective heat conductivity of two materials in the
temperature range T= 573–1473 K and the air-pressure range p= 1–10 5 Pa have been …
