RISA Converging Slot-Hole Film-Cooling Geometry—Part 1: Low-Speed Flat-Plate Heat Transfer and Loss
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents experimental measurements of the performance of a new film-cooling hole geometry—the converging slot-hole or console. This novel, patented geometry has been designed to improve ...
A Converging Slot-Hole Film-Cooling Geometry—Part 2: Transonic Nozzle Guide Vane Heat Transfer and Loss
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the first experimental measurements on an engine representative nozzle guide vane, of a new film-cooling hole geometry, a converging slot-hole or console. The patented console ...
Influence of Surface Roughness on Heat Transfer and Effectiveness for a Fully Film Cooled Nozzle Guide Vane Measured by Wide Band Liquid Crystals and Direct Heat Flux Gages
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of surface roughness on heat transfer coefficient and cooling effectiveness for a fully film cooled three-dimensional nozzle guide vane (NGV) has been measured in a transonic annular ...
