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 …

… 1024 J= kg K Specific heat capacity coolant: air … 1010 J= kg K Specific heat capacity
coolant: Ar … 525 J= kg K Specific heat capacity coolant: He …

A transient heat transfer technique using a heating foil and liquid crystals is described. The
basic idea is a step-heating technique, eliminating the local heat flux and the surface …

The following paper presents an iterative algorithm for the determination of porosity
distributions in a porous material applied for the cooling of gas turbine blades. Numerical …

The time and space development of the fluid bulk temperature in a transient heat transfer
experiment for internal channel cooling investigations using heater foils is addressed. An …

The film cooling performance on a convex curved surface subjected to accelerated free-stream
flow was investigated. The thermochromic liquid crystals technique was applied to …

The present paper deals with the investigation of transpiration cooling. A coolant is injected
through a porous ceramic matrix composite material into a channel where it is interacting …

In today’s rocket thrust chambers extremely high heat loads are apparent. Reducing these
loads in combination with a reduction of the thrust chamber’s structural weight can be …

The presented paper describes a method of solving the inverse problems of heat conduction,
consisting in solving the Poisson equation for a simply connected region instead of the …

The experimental and numerical heat transfer results in a trapezoidal duct with two staggered
rows of inclined impingement jets are presented. The influence of changes in the jet bore …
