APPLICATION OF TAGUCHI-GREY METHOD TO EVALUATE THE PERFORMANCE OF ENERGY PRODUCED BY USING TRILATERAL FLASH CYCLES AND LOW-GRADE RENEWABLE HEAT

Increased in population and automation of process have upsurge the demands of fossil fuels drastically. Although the solar, bio-mass, geothermal etc. energy renewable resources are easily available for extraction, the contemporary topics like very high initial costs and power developing costs have curtailed their progress. Improvements on current power production methods demand implementing a strong thermal system to draw energy from low-grade renewable heat sources as most of the present techniques can only extract high temperature resources and are very expensive. A proposed binary system having Trilateral-Flash-Cycle (TFC) and a reaction turbine would tackle the contemporary topics with low operation cost and widely utilize the available sources to generate direct power by means of a hydrothermal with the reduced greenhouse gas emissions. The performance characteristics measured were efficiency, Gross power and nozzle flow area have been optimized for input factors such as speed, isentropic efficiency, binary working fluids and turbine diameters using hybrid Taguchi based grey relation analysis (GRA) where experimental trials carried out with Taguchi L9 orthogonal array. The multiple response optimization and ranking of input parameters were productively completed by GRA to find the effect of each of it. Analysis of variance produced the higher significant factor from selected parameters with percentage of their contribution and was confirmed with an affirmation (verification) test for the obtained optimal set of factors. Thus, the hybrid GRA with Taguchi technique design provides the optimal design parameters affecting multi-performances of TFC system.
