Abstract :
Globally faster consumption of hydrocarbon fuel in the transport sector is posing threat to environmental and ecological imbalances and thereby depletion of hydro-carbon fuel is causing another challenge to oil reserves. In view of these issues extensive researches are being carried out to explore the alternative energy source and or to find out appropriate energy conversion system. The atmospheric air once compressed, it is found as potential working fluid to produce shaft work for an air turbine and releases almost zero pollution in the environment. This paper details the mathematical modeling of a small capacity compressed air driven novel multi-vanes type air turbine. Effect of expansion of high pressure air collected between two consecutive vanes at different vane angles and varying inlet pressure have been analyzed here. The study shows that the total shaft power is found optimum at injection angle 60° when vane angle θ=36° (10 vanes) and it reduces at injection angle 45° when vane angle θ=51.4° (7 vanes) and further goes down at injection angle 30° when vane angle θ=60°-72° (6-5 vanes), for injection pressure 6 bar and speed of rotation 2500 rpm.
