摘　　要：In this paper,based on the mixture flow model,an optimized six-flux model is first established and applied to the tubular solar photocatalytic reactor.Parameters influencing photocatalyst distribution and radiation distribution at the reactor outlet,viz.catalyst concentration and circulation speed,are also analyzed.It is found that,at the outlet of the reactor,the optimized six-flux model has better performances(the energy increase by 1900%and 284%,respectively)with a higher catalyst concentration(triple)and a lower speed(one third).
