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

MANY applications are confronted with the necessity to estimate the heat flux from a fluid
flow to a surface [1–4]. Especially when the surface is actively cooled, the determination of …

The turbulent flow and heat transfer in a rectangular channel without and with transpiration
cooling was investigated experimentally and numerically. The two-layer k–ε model was used …

Mean velocity and injectant concentration profiles are presented for the boundary layer on a
flat plate with air injection through rows of discrete holes. An 8/1 pitch/diameter ratio was …

Heat transfer behavior was studied in a turbulent boundary layer with full-coverage film
cooling through an array of discrete holes and with injection normal to the wall surface …

The overall cooling effectiveness of a plane 152 mm square transpiration wall was
measured on a simulated gas turbine combustion chamber. Boundary layer temperature …

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 …

This paper presents an experimental investigation of the performance of film and
transpiration cooling. Two circular tubes were used as test models, one consisted of sintered …

This article attempts to provide a cooling performance comparison of various mass transfer
cooling methods and different cooling media through two experiments. In the first …

Local values of heat-transfer rate and temperature-recovery factor, obtained on a
transpiration-cooled flat plate, are presented. Air was injected into a turbulent boundary …
