DESIGN AND PERFORMANCE ANALYSIS OF A NOVEL GASEOUS ORGANIC FLUID-POWERED PELTON TURBINE FOR WASTE HEAT RECOVERY AND SUSTAINABLE ENERGY GENERATION

Abstract

Diminishing reserves of fossil fuels and the surging global energy demand have revitalized the focus on harnessing greater
energy potential from the emissions emanating from internal combustion engines. Organic Rankine Cycle utilizes organic fluids,
emerged as a highly efficient method for capturing low-grade energy from exhaust gases. This process involves the organic fluid
absorbing heat from the exhaust gases and subsequently vaporizing. The resultant gaseous fluid is then directed towards a turbine to
extract mechanical energy.
Objectives of research are to prepare design and conduct an analysis of a Pelton turbine that can effectively generate mechanical
work utilizing gaseous toluene as its operational fluid. It is noteworthy that, thus far, Pelton turbines have been exclusively developed
for water as their working medium. Hence, this research represents a distinctive endeavor aimed at the development of Pelton turbines
employing gaseous fluids.
This work entails an exhaustive analytical design procedure encompassing the determination of critical parameters and dimensions.
Subsequently, CAD models are created based on the analytical design, followed by a comprehensive finite element analysis of pivotal
components. Furthermore, experimental validation of the proposed system is also carried out
