Pressure-loss and flow coefficients inside a chordwise-finned, impingement, convection, and film air-cooled turbine vane [PDF]
Total-pressure-loss coefficients, flow discharge coefficients, and friction factors were determined experimentally for the various area and geometry changes and flow passages within an air-cooled turbine vane.

The potential impact of Ocean Thermal Energy Conversion (OTEC) on fisheries [PDF]
The commercial development of ocean thermal energy conversion (OTEC) operations will involve some environmental perturbations for which there is no precedent experience. The pumping of very large volumes of warm surface water and cold deep water and its

Jet array impingement flow distributions and heat transfer characteristics. Effects of initial crossflow and nonuniform array geometry [PDF]
Two-dimensional arrays of circular air jets impinging on a heat transfer surface parallel to the jet orifice plate are considered. The jet flow, after impingement, is constrained to exit in a single direction along the channel formed by the jet orifice ...

Numerical solution for the temperature distribution in a cooled guide vane blade of a radial gas turbine [PDF]
A two dimensional finite difference numerical technique is presented to determine the temperature distribution of an internal cooled blade of radial turbine guide vanes. A simple convection cooling is assumed inside the guide vane blade. Such cooling has

Jet array impingement with crossflow-correlation of streamwise resolved flow and heat transfer distributions [PDF]
Correlations for heat transfer coefficients for jets of circular offices and impinging on a surface parallel to the jet orifice plate are presented. The air, following impingement, is constrained to exit in a single direction along the channel formed by ...
