Non Equilibrium

The chemical non-equilibrium flow of supersonic combustion ramjet (scramjet) nozzle is numerical simulated with different chemical kinetic models to research the effects on numerical results of the nozzle performance. The numerical results show that total temperature is increased due to the recombination of dissociation compositions and the combustion of the residual fuel. The effect of the combustion of the residual fuel is more obvious in this paper, and the effect to the performance of the nozzle is noticeable. The species of the compositions in the models influence the quantity of heat sending out when it get equilibrium, so the 9-species chemical kinetic models are more suitable in the simulation of the scramjet nozzle chemical non-equilibrium flows.

Non Equilibrium

A systematic search is made for semiconductor models displaying non-equilibrium phase transitions induced by recombination and generation processes. Formal conditions are elaborated for some typical classes of reaction kinetic models with a phase transition. Under this aspect various recombination and generation mechanisms involving electrons, holes and traps are surveyed systematically, and subsequently two new classes of band–trap models exhibiting first and second order phase transitions, respectively, are constructed.
