The Combined Effects of an Upstream Ramp and Swirling Coolant Flow on Film Cooling Characteristics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an experimental investigation on the performances of a new film cooling structure design, in which a ramp is placed upstream of a cylindrical film hole and a cylindrical cavity with two diagonal impingement ...
A Fundamental Study on the Chemical Stability of La1−xSrxCo0.2Fe0.8O3−δ Cathodes for Intermediate Temperature Solid Oxide Fuel Cells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The chemical stability of La1−xSrxCo0.2Fe0.8O3−δ (x = 0, 0.4, 0.6, and 1) oxides before and after annealing at 750 °C in air is investigated by field emission scanning electron microscopy (SEM), X-ray photoelectron ...
Numerical Investigation of Effects of Blockage, Inclination Angle, and Hole-Size on Film Cooling Effectiveness at Concave Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Film-hole can be often blocked by thermal-barrier coatings (TBCs) spraying, resulting in the variations of aerodynamic and thermal performances of film cooling. In this study, a numerical study of the blockage effect on ...
