Abstract

Therectangulardetonationflowfieldfilledwithhydrogen-airissimulatednumericallybased onmulticomponenttwo-dimensionalEulerequation,andeffectsofuniformincomingflowondetonationwavepropagationwerediscussed. Fromthenumericalresults,dependingontheflowvelocity, theapparentpropagationvelocityofadetonationwaveishigherintheupstreamdirectionandlowerin thedownstreamdirectionthanvC-J.Thepressureoftheupstream movingdetonationishigherthan thatofthedownstream movingdetonation.Asaresult,investigationofdetonationwavepropagation inaflowsystembyclassicalC-Jdetonationtheoryisunsuitable.
