Optimization of commercial net spacers in spiral wound membrane modules
CFD simulations have been used to determine mass transfer coefficients and power consumption of commercial net spacers. The simulations show transversal and longitudinal vortices, vortex shedding and instationary flow behavior leading to the enhanced mass transfer in spacer filled-channels compared to empty channels. The results of the simulations were validated with experiments and compared wi...
متن کاملthe role of application of dynamic assessment approach in improvement of iranian efl writing performance at different language proficiency levels
the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
Computational fluid dynamic analysis of RO membrane performance with novel feed spacer geometries
A finite element based numerical model has been employed to describe momentum and mass transfer in open and spacer-filled crossflow membrane channels. Simulations considering operating conditions typical of seawater (SW), brackish water (BW), and reuse water (RW) reverse osmosis (RO) applications are employed for optimization of hypothetical spiral wound element feed spacer designs. Preliminary...
متن کاملComparison the performance of different reverse osmosis membrane modules by CFD modeling
Reverse osmosis is a commonly used process in water desalination. Due to the scarcity of freshwater resources and wastewater problems, a lot of theory and experimental studies have been conducted to optimize this process. In the present study, the performance of reverse osmosis membrane module of salt–water separation was simulated based on computational fluid dynamics technique and solution-di...
متن کاملAdvanced Dynamic Simulation of Membrane Desalination Modules Accounting for Organic Fouling
A reliable dynamic simulator (based on a sound process model) is highly desirable for optimizing the performance of individual membrane modules and of entire desalination plants. This paper reports on progress toward development of a comprehensive model of the complicated physical-chemical processes occurring in spiral wound membrane (SWM) modules, that accounts for the...
