摘要：A theoretical mass-balance model based on the resistance-in-series approach and energy conservation in one-dimensional governing equations was developed and experimentally validated to predict permeate flux and temperature distributions. The decline in permeate flux across membrane modules is attributed to increased temperature polarization resistance in a flat-plate direct contact membrane distillation (DCMD) module for pure water production. The performance of DCMD modules was further optimized by introducing S-ribs carbon-fiber turbulence promoters with ascending and descending hydraulic widths, while also accounting for the accompanying rise in energy consumption. An economic analysis was also carried out to evaluate the trade-off between permeate flux enhancement and additional power consumption for various carbon-fiber-filled modules. The implementation of S-ribs carbon-fiber turbulence promoters into the hot saline feed stream resulted in permeate flux improvements with a maximum increase of 25.85% under the descending configuration compared to the module of using the no-carbon-fiber-filled channel. Results indicated that modules with descending hydraulic widths of 5∼4∼3 mm configuration exhibited a higher ratio In/Ip = 1.3 of permeate flux improvement to a relative lower specific power consumption compared to those with uniform hydraulic widths. Furthermore, a simplified expression for the Nusselt number was developed to generalize the heat transfer coefficient and predict permeate flux in modules incorporating these carbon-fiber promoters.
