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 …

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 …

A simple analytical procedure has been proposed to predict the wall temperature variations
due to transpiration cooling. Since the blowing flow through the porous wall strongly …

Heat transfer characteristics of transpiration cooling devices encompass Stanton numbers
and the temperature increase in the transpired wall. These were calculated for ideal …

A local thermal non-equilibrium analysis has been proposed for the gaseous transpiration
cooling in which a coolant gas is driven from a coolant reservoir through a wall of porous …

Transpiration cooling is an active cooling technique able to reduce thermal loads of
applications exposed to extreme operation conditions. A coolant is driven through a porous …

Comprehensive experimental and numerical studies were performed to determine cooling
film effectiveness of transpiration cooling over porous materials. The cooling film …

The influences of the thermal conductivity and porosity of the porous wall and locally
extraordinarily high heat fluxes on the hot surface and the location of a low porosity region …

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 …

The two-phase mixture model has been widely used to describe the performances of fluid
flow and heat transfer within porous media with liquid phase change. However, this model …
