Design and Development of Micro Turbine

Abstract

Micro turbines are a relatively new type of combustion turbine that produces both heat and electricity on a small scale. Micro turbines offer an efficient and clean solution to direct mechanical drive markets such as compression and air-conditioning. This report focuses on the design and development of a micro turbine driven by compressed nitrogen gas. The available literature regarding the design aspects of micro turbine were reviewed in detail. Gas turbine cycle and operation of micro turbine was studied and reported. The turbine blades and nozzles were designed with the help of Gambit software using a given set of cylindrical coordinates. The turbine has a radial inlet and axial outlet. A proper meshing scheme was used to mesh the turbine and nozzle assembly. CFD analysis was carried out by Fluent software to get the velocity vectors using a set of suitable inputs.
