(2010-01-14)The research focuses on testing the film cooling effectiveness on a gas turbine blade suction side surface. The test is performed on a five bladed cascade with a blow down facility. Four different blowing ratios are used ...
-
(2009-05-15)The hot gas temperature in gas turbine engines is far above the permissible metal temperatures. Advanced cooling technologies must be applied to cool the blades, so they can withstand the extreme conditions. Film cooling ...

An experimental investigation of turbine blade heat transfer and turbine blade trailing edge cooling (Texas A&M University, 2005-02-17)This experimental study contains two points; part1 turbine blade heat transfer under low Reynolds number flow conditions, and part 2 trailing edge cooling and heat transfer. The effect of unsteady wake and free stream ...
-
(2015-12-07)Very limited experimental data is available for aerodynamic and film cooling effectiveness under rotating condition in the literature. As a result, there is a strong need to study in detail and discover essential features ...
-
(2009-06-02)Film cooling effectiveness on a gas turbine blade tip on the near tip pressure side and on the squealer cavity floor is investigated. Optimal arrangement of film cooling holes, effect of a full squealer and a cutback ...
-
(2016-07-28)A comprehensive study was performed to investigate effects of geometrical and coolant flow parameters for a three row compound hole design over a flat plate. These included β: +45 and -45, in-line and stagger arrangement, ...
-
(Texas A&M University, 2006-10-30)The inlet temperature of modern gas turbine engines has been increased to achieve higher thermal efficiency and increased output. The blade edge regions, including the blade tip, the leading edge, and the platform, are ...
-
(2013-10-07)The need to reduce both the time and cost of product design has allowed numerical analysis to play an ever-increasing role in design cycle analysis. This is particularly true in the aerospace industry, where the use of ...
-
(2010-10-12)Gas turbine engines are extensively used in the aviation and power generation industries. They are used as topping cycles in combined cycle power plants, or as stand alone power generation units. Gains in thermodynamic ...
-
(Texas A&M University, 2005-02-17)This experimental study consists of two parts. For the first part, the film cooling effectiveness for a single row of seven cylindrical holes with a compound angle is measured on a flat surface using five different ...
-
(2009-05-15)The turbine blade platform can be protected from hot mainstream gases by injecting cooler air through the gap between stator and rotor. The effectiveness of this film cooling method depends on the geometry of the slot, the ...
