【 摘 要 】
One of the most important components in gas turbine power-plant are turbine blades, which flow of high pressure gases takes place and produce work. A Blade can be defined as the medium of transfer of energy from the gases to the turbine rotor. There exist a great drive in turbine industry to increase the turbine blade and vane cooling. In typical gas turbine engines nozzle guide vane (NGV) endure the highest operating temperature. Due to high operating temperatures and speeds, failure of the turbine blades is inevitable. Hence there is a pressing need for cooling of turbine blades. External and Internal cooling methods are the common techniques to reduce overall surface temperature distribution over the NGV. The design, analysis and modification of the gas turbine blade design have to be made, on which CATIA V5 and Turbo grid is used for design of solid model of the turbine. ANSYS 15 Software is used to analysis of model generated by meshing of the blade by applying boundary conditions. A heat transfer analysis has to be carried out to investigate the surface temperature of the blade by using some internal cooling techniques.
