摘要
通过对双接触式液柱塔内气液两相流场的模拟计算,发现在有、无液柱射流时,喷嘴数量增加对塔内床层压降有不同的影响。并对特定工况下的液柱塔流场进行CFD数值模拟,描述了塔内不同喷嘴数量不同液气比条件下气液流动状况。计算与试验结果吻合较好,表明所建立的模型和采用的算法具有良好的预测性和可靠性。
It is found that the increase in the number of nozzle will lead to different influence for pressure drop in the tower (with or without fluid column jet) through the simulation calculation of the gas-liquid two phase flow field in double contact liquid-column tower. Then taking the CFD numerical simulation of the particular condition, the condi- tion of gas flow is described in different nozzle number and different liquid air ratio. Calculation is well agreed with test results, which show that the model and the algorithm have good predictive and reliability.
