凡人善举

善良是开在心坎上最美的花,也是最宜人的。昨儿虽然是周末,但是我早早起床做饭,因为心里有一堆计划要干的活。早饭刚吃完,就听到敲门声。这么早会是谁来做客?我示意儿子去开门。儿子跑过去,随着门开,听到儿子叫了一声"爷爷,奶奶"。我一听是公婆如此早来,赶紧去门口迎,笑问:"这么早就到了,吃饭了吗?"婆母气喘吁吁地说:"吃了,你爸爸要来城里喝羊汤,就早来

Flow Field of Circulating Fluidized Bed Reactor with Venturi Inlet Configuration

Different two-equation k-ε models were used to simulate the gas flow field generated by a new type of circulating fluidized bed reactor with venturi gas distributor. The numerical results were compared with the experimental data. It has been shown that the simulation results from the standard k-ε model have the best match with the experimental data. Based on this model, the gas flow field in the venturi diffuser and riser was analyzed by the concept of velocity nonuniformity and dead zone percentage. Both the nonuniformity of gas velocity and the dead zone percentage reach the maximum at the venturi outlet due to the effect of the vortex. At the same time, it provides a good platform for the further optimization of the inlet configuration of circulating fluidized bed reactor.
