Thermodynamic Analysis of an Axial Vane Rotary Engine

Axial vane rotary engine (AVRE) is a novel type of rotary engines with special and exclusive features, under research in some of the reliable engine research centers around the world. The engine is a positive displacement mechanism that permits the four stroke action to occur in one revolution of the shaft with a minimum number of moving components. In this paper a zero dimensional combustion model is developed for a spark ignition axial vane rotary engine. Spark ignition engine cycle simulation has been performed on the equivalent four stroke reciprocating engine of the AVRE engine, with approximately the same cylinder volume variation versus crank angle as this rotary engine. Heat released from fuel and heat transfer to cylinder walls are simulated using wiebe function and woschni heat transfer correlation, respectively. The developed code for engine simulation in MATLAB is applied for another engine and there has been a good agreement between results of this code and results related to the engine chosen for validation. Finally pressure, heat flux, and heat transfer coefficient variations versus crank angle are presented for the equalized engine.
