Conjugate calculation methodology is used to simulate the C3X gas turbine vanes cooled with leading edge films of “shower-head” type. By comparing calculated results of different turbulence models with the measured data, it is clear that calculation with the transition model can better simulate the flow and heat transfer in the boundary layers with leading edge film by: The objective of this work was to develop design concepts for a cooled ceramic vane to be used in the ﬁrst stage of the High Pressure Turbine(HPT). To insure that the design concepts were relevant to the gas turbine industry needs, Honeywell International Inc. was subcontracted to provide technical guidance for this work. The work performed.
Design Concepts for Cooled Ceramic Matrix Composite Turbine Vanes To reduce emissions and improve fuel consumption in gas turbine engines This project demonstrated that higher temperature capabilities of ceramic matrix composites (CMCs) can be used to reduce emissions and improve fuel consumption in gas turbine Size: KB. The gas turbine’s efficiency increases with the turbine inlet temperature: advanced gas turbine engines operate today at very high temperatures (–K). As the temperature increases, the heat transferred to the turbine blade increases too, so that the operational life .

TBCs, which comprise metal and ceramic multilayers, insulate turbine and combustor engine components from the hot gas stream, and improve the durability and energy efficiency of these engines.
The second mould with two cavities for two types of experimental core shapes enabled the examination of small cross-section formation. The experimental cores had a length of over 30 mm and a minimal cross-sectional area of only 5 mm 2. Fig. 1 presents a photo of the two types of ceramic cores for the turbine blade.
