ROTARY PISTON EXPANDER ENGINE
A computer simulation and experimental study of a Wankel type engine for open-cycle or closed-cycle applications is conducted to demonstrate the rotary expander concept. An air-alcohol-water mixture is burned external to the expander in an experimental combustor and directed to the engine. Two rotary cylindrical valves are mounted on the engine housing; as a result, two complete working cycles are realized for each complete rotor face revolution. Side ports uncovered by the rotor side seals duct the expanded gases to the atmosphere. A water brake dynamometer serves as the load. Instrumentation sufficient for a thermodynamic analysis is provided. High response, flush-mounted pressure transducers are employed to obtain indicator card (pV) data for the working cycle. The engine is run at 4800 rpm, delivering 114 kW (153 brake horsepower), for 4 minutes as a maximum performance test. This requires delivery conditions of about 414 kPa (600 psia) and 538 c (1000 f) at the inlet valves.
