چکیده
|
For achieving a successful membrane distillation, not only the membrane performance but also the module design is important# an acceptable membrane must have a high salt rejection along with a high permeate flux# since the driving force for membrane distillation is a temperature gradient across the porous hydrophobic membrane, the temperature polarization could affect the system performance considerably# computational fluid dynamics (cfd) is a powerful tool for the investigation of the temperature polarization in a membrane module# in this research, the effects of module length on the temperature polarization coefficients (tpc) is investigated# the results showed that an increase in the module length results in a decreased temperature polarization and higher tpc# however, there is optimum module length value for attaining an optimum dcmd operation#
