Compressed Air Energy Storage System Based Engine for Running Light Vehicle

Abstract

Globally excessive consumption of hydrocarbon fuel in transport sector is a serious threat to the civilization due to paucity of fuel in future. Also this growing use of vehicles for transport is contributing about 70% of total air pollution and causing environmental and ecological imbalances. Thus the worldwide fast depletion of conventional energy resources and impact of emissions on environment necessitates the search of alternative non- conventional energy sources, and other direct conversion of energy systems. This paper deals with study of sustainable renewable energy resources and their conversion system. Efforts have been made to develop emission free compressed air engine for better and sustainable energy future. Here parametric study of a vane type novel air turbine is carried out. The optimum power output obtained ranges from: 1.0 kW, 4.0 kW and 9.0 kW at D= 50 mm, 100 mm and 150 mm respectively, when rotor/ casing ratio (d/D) = 0.70, vane angle (θ) is kept 30o to 45o (vanes =12 to 8 nos.), and other parameters such as: injection angle (60o), injection pressure (6 bar) and speed of rotation (2500rpm) are kept constant throughout the study.
