Numerical Simulation of the Integrated Solar/Hybrid Desalination System

A mathematical model is developed to predict the performance of the integrated solar/hybrid desalination system. The novel hybrid desalination system in this study consists of multi-stage thermal vapor compression (TVC) system and spiral wound air-gap membrane desalination (AGMD) units. The hot brin...
