A CFD study on the Effect of Spacer Orientation on Temperature Polarization in Membrane Distillation Modules

Computational fluid dynamics (CFD) study in this work examines the effect of spacer orientation, inlet velocity and filament spacing on shear stress distribution and temperature polarization in membrane distillation modules. The CFD simulations show that spacer orientation affects the temperature p...
