Design of cone-and-plate test cell for ultrafiltration

In ultrafiltration (UF) processes, the mass transfer coefficient depends on the hydrodynamic shear at the membrane surface. Unfortunately, in all the existing UF test devices, shear stress is non-uniform and only an average value is used. This paper discusses the theory, design, fabrication, and experimental validation of a next-generation cone-and-plate test cell (CPTC) to carry out UF under uniform surface shear of 2 μ ω secθ1 Pascals (where …
