Effects of a ceramic coating on metal temperatures of an air-cooled turbine vane by Herbert J. Gladden Download PDF EPUB FB2

An experimental study was made to determine the effects on metal temperatures of using the NASA thermal-barrier coating system on an air-cooled turbine vane and to quantify the beneficial effects of this coating compared with the same vane without the ceramic coating.

Thermal barrier coating (colored white) on a turbine guide vane in a V turbofan engine Thermal barrier coatings (TBCs) are advanced materials systems usually applied to metallic surfaces operating at elevated temperatures, such as gas turbine or aero-engine parts, as a.

that the use of these ceramic coatings can reduce metal temperatures and coolant flow requirements or increase allowable turbine-inlet temperatures. The tests of refer-ence 1 also demonstrated the durability of a coating of calcia stabilized zirconia over a bond coat of Nichrome.

This coating satisfactorily completed hours of steady-state. These bolts were air-cooled to prevent the elongation of the bolt causing the plates to be rooted out by air getting behind the metal plates causing major damage to the turbine blades.

The metal plates with the metal screws were still maintained in the last row of plates as. The aim of this paper is to numerically investigate cooling performances of a non-film-cooled turbine vane coated with a thermal barrier coating (TBC) at two turbulence intensities (Tu = % and.

Jul 08,  · Conjugate heat transfer investigation on the cooling performance of air cooled turbine blade with thermal barrier coating. Thermal barrier effects of the coating vary at different regions of the blade surface, where higher internal cooling performance exists, more effective the thermal barrier will be, which means the thermal protection Cited by: 2.

A turbine blade is the individual component which makes up the turbine section of a gas turbine or steam veterans-opex.com blades are responsible for extracting energy from the high temperature, high pressure gas produced by the veterans-opex.com turbine blades are often the limiting component of gas turbines.

To survive in this difficult environment, turbine blades often use exotic materials like. These parts are all air cooled through the first stages internal passages. (The second stage blades and on down are not internally cooled.) The concern raised in many gas turbine institutions is that the metal temperatures of these hot parts, due to the heat conductivity properties of injected steam, will make them deteriorate veterans-opex.com: Dah Yu Cheng, Albert L.
