Mathematical Simulation of Combination Process of SHS Jiang Shihong; Guan Changsheng; Wang Weiming(Lect.,Wuhan Institute of Chemical Technology,Wuhan 430073,China.)In this paper we have reviewed several mathematical models of combination process of SHS,and illustrated that the mathematical simulation method is a complement of laboratory study in the SHS research. Forethemore,we have discussed the permeate combustion model,and the mathenatical solution.: combination of SHS; methematical model ; permeate comustion
