Solar Energy Driven Membrane Desalination: Experimental Heat Transfer Analysis
نویسندگان
چکیده
In the direct contact membrane distillation (DCMD) system, temperature polarization due to boundary layer formation limits system performance. This study presents experimental results and heat transfer analysis of a DCMD module coupled with salinity gradient solar pond (SGSP) under three different flow channel configurations. first case, feed permeate channels were both empty, while in next two cases, filled porous spacer material. Two geometries are examined: 1.5 mm thick filament angle 65°, 2 90°. The considers only conduction by replacing hydrophobic normally used thin polypropylene sheet so that no mass can occur between channels. Reynolds number for all configurations was found be 1000 2000, indicating regime laminar. rate through sides same, experiments conducted rates 5 L/min 3 L/min. It has been highest overall coefficient obtained thickness

An experimental study of solar thermal vacuum membrane distillation desalination
An experimental desalination system coupling a vacuum membrane distillation (VMD) unit and a vacuum tube solar heat collection (SHC) unit was developed and tested. The parametric sensitivity of the VMD unit performance was investigated first using an electric heater as the heat source, and then the whole system was examined using solar heat. It was revealed that hot feed temperatures higher tha...

متن کاملHeat Transfer and Geometrical Analysis of Thermoelectric Converters Driven by Concentrated Solar Radiation
A heat transfer model that couples radiation/conduction/convection heat transfer with electrical potential distribution is developed for a thermoelectric converter (TEC) subjected to concentrated solar radiation. The 4-leg TEC module consists of two pairs of ptype La1.98Sr0.02CuO4 and n-type CaMn0.98Nb0.02O3 legs that are sandwiched between two ceramic Al2O3 hot/cold plates and connected electr...
متن کاملSolar-Driven Integrated Ro/Nf For Water Desalination
This article presents an experimental study where two different modules are integrated, i.e. a reverse osmosis (RO) module, and a nanofiltration (NF) module, for brackish water desalination unit. Photovoltaic (PV) panels power the setup. The performance for each of the modules was evaluated separately. Then both modules were integrated together, either in series or in parallel. The performance ...
