The permeation properties, incorporated with a transient unsteady hydrodynamics modeling approach, were used to analyze and optimize the ML value for SWM feed spacers. The influence of unsteady hydrodynamics on the development of the concentration polarization in the membrane channel was also investigated. The optimum ML ratio was determined to be 3, because of its ability to generate a high intensity of unsteady hydrodynamics with the lowest effective concentration polarization factor and the results were further validated using velocity vector plots, wall shear stress analysis, and the localized concentration polarization factor. © 2010 American Chemical Society. date: 2010 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-77953355518&doi=10.1021%2fie9017989&partnerID=40&md5=a8c1905e0bfb859244e3efe3a7c05996 id_number: 10.1021/ie9017989 full_text_status: none publication: Industrial and Engineering Chemistry Research volume: 49 number: 12 pagerange: 5834-5845 refereed: TRUE issn: 08885885 citation: Lau, K.K. and Abu Bakar, M.Z. and Ahmad, A.L. and Murugesan, T.
