CFD ANALYSIS OF RADIAL FLOW MICRO GAS TURBINE

A turbine blade is the vital component of a gas turbine. The turbine blades are frequently the restricting factor of gas turbines. To survive in this difficult environment, turbine blades generally use distinct materials like notable alloys and lots of exceptional methods of cooling, which includes inner air channels, boundary layer cooling, and thermal barrier coatings. In this project, a turbine blade is designed and modeled in 3D modeling software CREO. The design is modified by changing the base of the blade to increase the cooling efficiency. Since the design of turbo machinery is complex, and efficiency is directly related to material performance, material selection is of prime importance. In this project, two materials and two different gas flow conditions (laminar and turbulent flow) are considered for turbine blade.. Optimization is done by varying the materials Titanium alloy and Super Alloy by performing conjugated field analysis (hot structural) on the turbine blade for both the designs.
