This paper reports on our research in developing a micro power generation system based on gas turbine engine and piezoelectric converter. The micro gas turbine engine consists of a micro combustor, a turbine and a centrifugal compressor. Comprehensive simulation has been implemented to optimal the component design. We have successfully demonstrated a silicon-based micro combustor, which consist...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
Aiming at the problems existing in fault diagnosis of Distributed micro gas turbine, a kind of new information system frame of fault Diagnosis on Distributed micro gas turbine is proposed in this paper. The consumers and the manufactures contact with each other through Internet, share the corresponding data of the Distributed Micro-turbine, and diagnose and solve the faults together. Through th...
One of the options being examined in last decades in the development of environmentally sustainable, energy-efficient and lightweight vehicles is the replacement of piston engines by gas turbine engines, especially in hybrid vehicles. A lot of effort has been consistently put in design and production of concept hybrid automobiles powered by gas turbine engines by leading automobile producers su...

In this study, a combination of micro gas turbine, absorption cooling, and organic rankine cycle is selected. The system is modeled applying the laws of thermodynamic, and based on this model, exergy and economic analyses are performed for each component of the system. Four design variables, namely compressor pressure ratio, turbine inlet temperature, turbine efficiency, and compressor efficien...
Gelcast ceramic materials have great potential in the application in millimeter and micrometer objects, such as micro gas turbine engines. To build a complex-shaped ceramic part which is unavailable for conventional fabrication techniques, µMold Shape Deposition Manufacturing (µMold SDM) is developed and designed. Material issues, such as compatibility, shrinkage, thermal property and surface q...
The following analysis is presented to serve as a preliminary design guide for micro turbine engine designers to consider the potential advantages of incorporating the Rampressor into their recuperated engine designs. It is shown that the increase in compressor efficiency and the shift in optimum pressure will increase the efficiency of the engine and lower the recuperator inlet temperature and...
