Study on the integrated utilization of seawater by solar chimney

摘要

Aiming at the problems in the desalination and the low efficient of the solar chimney, the integrated system has been put forward, which enhances seawater evaporation by solar chimney, forms high speed airflow at the base of chimney, gains fresh water by condensation. Direct and indirect condensation has been researched to find an efficient way and the effect on enhanced evaporation by temperature and velocity of airflow was studied independently. For the sake of learning the law of micro heat transfer and mass transfer, to find the theoretical basis on system of scale-up, numerical simulation was carried out by Fluent. Base on the results of experimental and simulation it is an economic feasible system that can bring fresh water and produce electricity by water or wind.
