Turbomachines design and performance evaluation of 30 KW micro gas turbine generator
Abstract:
The need of electrical power is still growing explosively in most parts of the world including Thailand. Although, the electric power from a large power plant is in Megawatts, the electric energy insufficient crisis still occurs. An alternative way to generate electricity with a microturbine is motivating because of their major attributes include low emissions, multi-fuel capability, compact size, high reliability, and low maintenance. Basically, the micro gas turbine operates under Brayton cycle and consists of three main components that are compressor, turbine, and combustion chamber. A recuperator is included in the cycle in pursuance of increasing efficiency. Since the high performance micro gas turbine originates from the outstanding design of turbomachinery. Therefore, the turbomachinery design configuration is an important part that needs to be considered in order to develop the high performance micro gas turbine generator. This dissertation aims to investigate for an optimum design of turbomachinery for 30 kilowatts micro gas turbine generator based on the theory of thermodynamics, fluid mechanics and component matching. The computational fluid dynamics was applied to visualize flow in the designed component and the numerical solutions obtained from the CFD method were verified against the analytical solution from the designed parameter. The performance curve of turbomachinery was constructed and then developed to the performance curve of micro gas turbine
