Abstract

Fromthephysicaldefinitionofperturbationpropagation(Machwaves),thecharacteristic equationsofatwo-dimensionalsupersonicflowwerededucedintotheformswhichwereuncorrelated withtheformulaofEOS.Meanwhile,anewPrantl-Meyerfunctionwasexpressedintoasimplevariablefunctionoffluiddensityalso. Basedoncharacteristicdifference,asolutionmethodofthetwo-dimensionalsupersonicflowwasbuiltup. Therefore,asanapplicationexampleofthesolutionmethod, themovementoftheflyerplatedrivenbyglancingdetonationwasanalyzed.Forcomparison,DetonationdrivesoftheTNTandemulsionexplosiveswerecalculatedwithJWLandpolytropicEOSs. The numericalresultsshowthatcharacteristicdifferencesolutionscompletelyagreewiththeexpanding worksofexplosiveEOSs.
