Abstract

In this paper, the field synergy principle is used to simulate the mass transfer performance of hollow fiber membrane modules under vibration conditions. The mass transfer characteristics of hollow fiber membrane modules are investigated by changing the vibration frequency, amplitude and fluid velocity. The results prove that: the average field synergy number under vibration conditions is much higher than that under the non-vibration condition. The average field synergy number increases with the frequency and amplitude. But the increase of vibration frequency and amplitude does not linearly improve the mass transfer performance of the hollow fiber membrane modules. Compared with the increase of amplitude, the enhancement effect of increasing frequency on mass transfer is more obvious. With the increase of the vibration energy consumption, the mass transfer efficiency of the hollow fiber modules increases. With the increase of flow velocity, the average field synergy number shows a decreasing trend, meaning that the degree of synergy between the velocity field and the concentration field decreases. While the Reynolds number will increase with the flow velocity, which will enhance the mass transfer performance of the hollow fiber membrane modules.
