Lessons Learnt from the Ultra-Micro Gas
The outcome of NEDO supported international research project led by University of Tokyo is reviewed, with respect to developing key technologies for ultra-micro gas turbines (UMGT). The study suggested ‘Finger-top’ gas turbines as a currently feasible extreme that install rotors of 8 mm in diameter with 1.2 million rpm to produce tens of watts net output. Prior to practicing such UMGT system in...
متن کاملAero-Thermal Research Particulars in Ultra-Micro Gas Turbines
Aerodynamics in turbo-components and matched combustor characteristics relating to the design of ultramicro gas turbines (UMGT) were presented. Some detailed analysis were provided for the effects of heat transfer, tip clearance and geometrical restriction imposed to UMGT flow passages, as well as a leading concept of combustor design to achieve micro flame structure for enhanced efficiency and...
متن کاملAnalysis of micro-recuperators in small-sized gas turbines –manufacturing potential of Iran
Heat recuperation is often used to improve the overall cycle efficiency of gas turbines. However, generally in small- scale gas turbines, it has a negative effect on turbine inlet temperature, pressure ratio and pressure drops, and thus decreases the overall cycle efficiency. In this paper, a thermodynamic model is performed to evaluate recovered heat as a function of heat exchanger effecti...

متن کاملTechno-Economic Analysis of Different Energy Storage Technologies
Overall structure of electrical power system is in the process of changing. For incremental growth, it is moving away from fossil fuels major source of energy in the world today to renewable energy resources that are more environmentally friendly and sustainable [1]. Factors forcing these considerations are (a) the increasing demand for electric power by both developed and developing countries,...
