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 …

I. INTRODUCTION An answer to the ever-increasing demands for materials able to
withstand very high temperatures may be sought either in the development of new materials …

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 …

Porous Coolin $ Elements. The method of transpirational cooling of structures on which
external convective or radiant heat flows of high density act (see Fig. i) has a number of …

SUMMARY A method of coping with the high rates of heat transfer encountered in the field of
jet-propulsion consists of making the parts to be cooled of a porous material and forcing the …

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 …

Introduction r^ HE results of experimental and theoretical studies of gaseous sweat cooling
described previously (1, 2) 3 have 3 Numbers in parentheses indicate References at end of …

One-dimensional two-phase flow transpiration cooling through porous metal is studied
experimentally. The expe~ imental data is compared with the one-dimensional analysis of …

The first part of an experimental and theoretical investigation into the feasibility of
transpiration cooled combustion chambers is discussed, as well as the design and testing of …

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 …
