Numerical and Experimental Investigations for Design of a High Performance Micro-hydro-kinetic Turbine

Design and manufacturing of a high performance micro-hydro-kinetic turbine is discussed in the present paper. The main goal is manufacturing an equipped experimental model of hydro-kinetic turbine with highest energy absorption from water current. A multi-shape ducted turbine comprised of a multi-part diffuser was manufactured that can be converted to many experimental models for studying vario...

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...

Micro Gas Turbine Range Extender - Validation Techniques for Automotive Applications

A Micro Gas Turbine (MGT) can be considered as an alternative to the internal combustion engine as a range extender for electric vehicles. The MGT produces less raw exhaust gaseous emissions such as HC and CO in aerospace and static applications compared to the internal combustion engine. In addition, the MGT weight is less than an equivalent internal combustion engine and potentially can reduc...
