Abstract: Calculations are presented which suggest that useful amounts of rainfall might be produced economically in and regions near seas or lakes. The proposed technique involves the coating of a large area with asphalt to produce ...

Abstract: Cooling of turbine hot-gas-path components can increase engine efficiency, reduce emissions, and extend engine life. As cooling technologies evolved, numerous blade cooling geometries have been and continue to be proposed ...

Abstract: Effective internal and external cooling of airfoils is key to maintaining component life for efficient gas turbines. Cooling designs have spanned the range from simple internal convective channels to more advanced double-walls ...

Abstract: The aerothermal characterization of film-cooled geometries is traditionally performed at reduced temperature conditions, which then requires a debatable procedure to scale the convective heat transfer performance to engine ...
