Investigation of Low-Temperature Desalination Process by Flashing, PV-Thermal, Thermal Storage, and Magnetized Nanofluids

Modeling of the PV-thermal solar collector and thermal storage PCM using magnetized nanofluids to power multi-stage flashing chambers desalinate seawater has been presented. The proposed model was established after mass energy conservation equations were written for finite control volume with properties heat transport fluid. studied presented hereby are Ai2O3, CuO, Fe304, SiO2. At different magnetic fields up 3000 Gauss, multiple chamber process under various conditions, including radiations, brine flows concentrations, temperatures pressures. Solar radiations taken as 500 w/m2, 750 1000 finally, 1200 w/m2. Nanofluids volumetric concentrations considered varied from 1% 20% There is clear evidence that higher radiation, flashed flow produced. results also clearly showed irreversibility reduced by nanofluid Ai2O3 at 10% compared water base highest experienced when used a fluid, lowest associated increase depends upon type its thermodynamic properties. Furthermore, concentration, availability last chamber. However, progressively Finally, predicted well experimental data published in literature.
