Effect of spacer orientation on the performance of direct contact membrane distillation

Y. Taamneh*, Jordan University of Science and Technology, Jordan

The effect of the presence of spacers and their orientation on the flow pattern and heat transfer enhancement for a commercial direct contact membrane distillation module was conducted. In this research, both experimental and computational fluid dynamics (CFD) simulations are carried out when the two sets of spacer filaments are oriented at an angle of 45 o to the channel axis and also when the top filaments are oriented at an angle of 30o, 45o, 62o and 90o while the bottom filaments are being parallel to the direction of flow. Besides predicting the Nusselt number and the total drag coefficient, the simulated results allow deeper understanding of the role of spacer presence and its filaments orientation in permeate flux augmentation . It is found that the degree of enhancement in heat and mass transfer depends on filaments orientation of spacers. The simulated results show that...
