用减压膜蒸馏测定对流传热系数的研究

Measurement of convective heat transfer coefficient by vacuum membrane distillation

介绍了应用减压膜蒸馏技术测定膜组件对流传热系数的理论方法 ,并通过实验测定了膜组件的对流传热系数。实验结果得到的关联式与Dittus Boelter方程基本一致。

Vacuum membrane distillation (VMD) experiments were performed to evaluate the heat transfer boundary layer resistance in a laboratory scale membrane module. A heat transfer correlation was obtained and used to calculate the flux of air gap membrane distillation(AGMD), the result approximately agreed with the Dittus Boelter equation.
