摘 要：Starting from the mass conservation and energy conservation of hotspot,the dynamics of hotspot combustion involving shell-mix are constructed by recalculating the special internal energy and heat capacity,in which the bremsstrahlung radiation loss and other energy transfer are *** the power balance in the hotspot,the relations between the fractions of shell-mixing in the hotspot and the ignition threshold and self-sustainable combustion are *** theoretical analysis and numerical simulation show that the enhancement of radiation loss induced by the shell-mixing plays the dominated role in the failure of *** adjusting different materials and the mixing fraction,the effects to the combustion paths are studied.
