Turbine blade coolingPROBLEM TO BE SOLVED: To improve turbine engine performance by cooling a turbine blade.ディパンカーパルジェームスイートンプソン
Turbine designers have the challenging task of getting the external and internal blade aerodynamics right while minimizing the use of cooling air. They need to accurately determine the location, the density, the pattern, the shape and the size of cooling holes to maximize blade life. Hole ...

A sufficiently low blade material temperature can only be achieved by combining thermal barrier coatings, alloys that are temperature-resistant, and external and internal convective cooling. As a result, typical impingement cooling or film cooling is an vital part of the cooling strategy. The ...
An air-cooled turbine blade having a plurality of serially spaced cavities therein is provided with cooling air inlets at its base. One of the inlets directs a cooling flow into a cavity proximate the
This shift in coolant flow toward the blade suction side, as opposed to the PS in stationary studies, can primarily be attributed to the effects of the blade relative motion. 展开 关键词: Pressure Rotation Coolants Turbine blades Blades Film cooling ...

Cooling holes are generally dispersed throughout the blade and connect the internal cooling passages with the outer surface of the blade. The steady stream of exiting air creates a film on the blade surface that additionally protects it from exposure to the hot gas. The cooling effectiveness and...
