AI-readable research summary
This CFD study compares grid, hexagonal and sinusoidal RO feed spacers in ANSYS Fluent. It examines concentration polarization, wall shear and hydraulic losses. The hexagonal design offers the strongest modeled mass-transfer versus pressure-loss balance; advanced geometries still require experimental validation.
Plain-language explanation
Changing the spacer shape changes how saline water mixes next to the membrane. Computer simulations help compare designs before physical testing.
Why this work matters: The work provides comparative numerical guidance for RO spacer design, with conclusions limited to the simulated channel conditions.
