# 多效蒸馏/多级闪蒸太阳能海水淡化系统数值模拟：第2部分——系统工作特性及影响因素分析Numerical Simulation of Multi-Effect Distillation/Multi-Stage Flash Desalination System Powered by Solar Energy: Part 2——The System Operation Characteristics and Analysis

Abstract: Based on the determined desalination system driven by solar energy and the structure parameters of the dis- tillatory in the system, the system operation characteristics were analyzed by numerical simulation under the conditions of solar intensity and ambient temperatures at June solstice in Guangdong. The system has five effect distillations. By changing the system starting temperature, strong brine circulation ratio, cooling seawater temperature and atmosphere transparency, the operation parameters of the system like the hot water temperature in the hot water reservoir, transient water produced rate and performance coefficient of the system were obtained by simulation, in which the solar collector area and structure parameters of the distillatory are invariant. The results are helpful for the system operation.
