摘要

以热空气吹掠型太阳能蒸馏器为研究对象,利用数值模拟结果和均匀设计法分析蒸馏器内流动与传热场协同角的变化规律和影响因素。结果表明,影响场协同角的主要因素是热空气进口速度,热空气进口温度和水温的影响不显著。在蒸馏水温30~70 ℃、进口空气温度40~90 ℃,进口空气速度为8 m/s时平均传热场协同角最小,为73.14°,传热系数最大,可达到同等条件下自然对流传热系数的4倍。

Abstract

In this paper, the hot air swept solar distiller is taken as the research object. Based on the numerical simulation results and uniform design method, this paper analyzes the variation law and influencing factors of the synergistic Angle between flow and heat transfer field in a solar distiller with hot air blowing. The result shows that the main factor affecting the field synergy Angle is the hot air inlet velocity, the influence of hot air inlet temperature and water temperature is not significant. When the distilled water temperature is 30-70 ℃ and the inlet air temperature is 40-90 ℃, the average heat transfer field synergy Angle is the minimum （73.14°） when the inlet air speed is 8 m/s. At this time, the heat transfer coefficient is the maximum, which can reach 4 times of the natural convection heat transfer coefficient under the same conditions.
