缺水和盐度是影响干旱半干旱地区植物生长的关键因素，在干旱半干旱地区经常遇到灌溉缺水和浅含盐地下水位毛细上升的问题。本研究的目的是在约旦裂谷干旱区建造太阳能海水淡化厂原型，建立预测原型内热动力学的数学模型，用实测的物理参数校准模型参数，并讨论原型的性能及其在不同环境下对其他地区的适用性。实测和数值模拟结果表明，该模型能较好地再现海水淡化厂的热动力学，并能预测出产露量。总的来说，所建立的模型为描述和解释所开发的海水淡化厂的质量和能量平衡机制提供了良好的基础。该研究也为分析和评估这种脱盐装置的产露量和热动力学提供了一个有用的工具。利用构建的原型，进行了基于作物种植的性能分析。
Water shortage and salinity are crucial factors affecting plant growth in arid and semi-arid regions, where irrigation water shortage and capillary rise from shallow saline water tables are often encountered. The objectives of this study are to construct a prototype of solar driven desalination plant in an arid area of Jordan Rift Valley, to develop a mathematical model predicting thermal dynamics in the prototype, to calibrate model parameters with measured physical parameters, and to discuss the performance of the prototype as well as its applicability to other areas under different environment. Results of measurement and numerical simulation show that the model is capable to reproduce the thermal dynamics of the desalination plant and to predict dew yield. Overall, the developed model provides a sound basis for describing and explaining the mass and energy balance mechanisms in the developed desalination plant. This study offers also a useful tool for analysis and assessment of the dew yield and thermal dynamics of such a desalination plant in general. Using the constructed prototype, performance analysis based on crop cultivation is ongoing.
