Simulation and Test for Turbine Air Powered Engine

Abstract

Turbine Air Powered Engine (TAPE) is a new type engine which has the character of zero emission, no pollution. Mathematical models of TAPE were established by the method of exergy analysis, the overall exergy and the exergy loss after reduced pressure with throttling were simulated in this paper. The results show that the maximum exergy loss of system is 60% during the process of reduced pressure with throttling, so the type of throttling decompression is not suitable for the system of TAPE which has bigger pressure reducing ratio. The results of bench test indicate that output power increases with the increase of inlet pressure within the scope of less pressure, and the regulation is similar to the simulating result. In the hybrid system of pneumatic internal-combustion engine, the measure which the air powered system is used in low-speed stage and the internal combustion engine powered system is adopted in high-speed stage can effectively solve the problem which the fuel consumption of the internal combustion engine is too bigger at low speed.
