“…Number of parameters affect the combustion was very large when testing a new engine design. By following literature [4][5][6]8 and previous research related to the rotary engines helped to reduce most of the parameters for the initial case setup. Five parameters were identified as the most important for the first parametric study.…”

A numerical computational model was developed to replicate the single rotor rotary engine with all three chambers. A Mesh was generated using GAMBIT 2.4. Dynamic mesh motion was defined using a user defined motion profile inside the ANSYS FLUENT. The combustion model used can represent both injection and spark ignition models simultaneously. A parametric study was performed followed by an optimum injection analysis to understand the effects of the injector and spark plug when located at different locations. Nomenclature DISI = Direct Injection Spark Ignition K = Turbulent kinetic energy ε = Turbulent dissipation CFD = Computation Fluid Dynamics DPM = Discrete phase modeling DOE = Design of Experiments PISO = Pressure implicit with splitting of operators bTDC = Before top dead center TDC = Top dead center aTDC = Before top dead center CA = Crank angle CO 2 = Carbon Di Oxide
