The efficiency of mass transfer in 60% fraction of hole is higher than in 40% fraction of hole. When gas/liquid ratio is lower 10, the efficiency of mass transfer in new sieve baffle tray is higher than in traditional tray.A three-dimensional quasi-single phase computational fluid dynamics program with the RNG- turbulence model is presented for evaluating the performance of the new sieve baffle tray. The special feature of this model is taking into account the influence of heat transfer during the mass transfer and the influence of mass transfer in computing the flow field.

建立了以RNG模型为基础的三维拟单相流模型，该模型与其它研究者所建立的模型的最大进步是，前人在塔板流场的计算中没有考虑传质的影响，并且在传质过程中没有也没有考虑传热对传质产生的影响，实际上在传质过程中，抛开传热来计算和研究传质是不准确的，因为在传质过程中伴随着传热，并且传热和传质是互相影响、互相制约的，本文所建立的传热与传质模型，把传热和传质进行了有效的藕合。
