The paper presents to discuss an effective energy conversion through isothermal combustion during the expansion process, herein an analytical code is exploited for compressible fluid by taking into account the swirl flow and changes of cross sectional area along the flow direction as well. Based on the premise of homogeneous swirl flow, a pseudo 3-dimensional mathematical model is feasible to formulate and to discuss the effects of swirl flow, duct configuration, exothermic reaction rate on energy conversion.
