Film cooling and thermal barrier coating are the most common external cooling techniques
used for gas turbine components. In film cooling, coolant air is brought to the external …

Transpiration cooling is an effective method to protect high heat flux surfaces such as rocket
combustion chambers. However, this technology is currently not applicable for turbine …

The last 50 years has witnessed significant improvement in film cooling technologies while
transpiration cooling is still not implemented in turbine airfoil cooling. Although transpiration …

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 …

Transpiration cooling is one of the most efficient cooling technologies to protect hot section
components such as turbine airfoils, missile heads and shells of rockets or space craft. This …

The last 50 years has witnessed significant improvement in film cooling technologies while
transpiration cooling is still not implemented in turbine airfoil cooling. Although transpiration …

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

Panels were tested at different locations around the turbine blade, on both suction and
pressure surfaces. Three different surface porosities were also tested. Results demonstrated …

Transpiration cooling is able to provide more uniform coolant coverage than film cooling to
effectively protect the component surface from contacting the hot gas. Due to numerous …

Transpiration Cooling is an effective cooling technology to protect hot section components
