In this study, a new perspective was introduced to conventional solar pond technology to spread its commercial application. In order to make it more useful with preserving energy efficiency, the brine layers were replaced with the normal freshwater by using a separated transparent partition. Structurally modified three different solar ponds were proposed and numerical investigations were conducted by using discrete ordinate method (DOM). For this, four types of solar ponds were modeled, the first one is the conventional salt‐gradient solar pond and three others are modified versions which are named as “Pure Water Solar Pond.” For all models, a comprehensive finite element method was developed to investigate the daily performance of solar ponds by using commercial software COMSOL. Salt‐gradient solar pond consists of seven layers where one layer is the heat storage zone, five layers are nonconvective zone, and one is the upper convective zone. However, in the modified models, solar ponds consist of two glass layers and one to three pure water zones depending on the model types. The numerical method includes a novel approach to calculate all the zone where absorption, emission, scattering, transmission, convection, and radiation are taken into account. Numerical results for all models were compared with an experiment to correlate the numerical accuracy of the DOM with anisotropic scattering phase function. Results indicate there is a good correlation between these four model approach and the experiment.

常规太阳能池技术提高热效率的新视角

在这项研究中，对传统的太阳池技术进行了介绍，以推广其商业应用。为了使其在保持能源效率方面更加有用，通过使用分离的透明隔板将盐水层替换为普通的淡水。提出了结构修改的三个不同的太阳池，并使用离散纵坐标法（DOM）进行了数值研究。为此，对四种类型的太阳能池进行了建模，第一种是常规的盐梯度太阳能池，另外三种是经过修改的版本，被称为“纯水太阳能池”。对于所有模型，通过使用商业软件COMSOL，开发了一种综合的有限元方法来研究日光浴池的日常性能。盐梯度太阳池由七层组成，其中一层是储热区，五层是非对流区，一层是上部对流区。但是，在修改后的模型中，根据模型类型的不同，太阳能池由两层玻璃层和一到三个纯水区组成。数值方法包括一种新颖的方法，可以计算所有考虑吸收，发射，散射，透射，对流和辐射的区域。将所有模型的数值结果与实验进行比较，以将DOM的数值精度与各向异性散射相位函数相关联。结果表明这四种模型方法与实验之间具有良好的相关性。在修改后的模型中，根据模型类型的不同，太阳池由两层玻璃层和一到三个纯水区组成。数值方法包括一种新颖的方法，可以计算所有考虑吸收，发射，散射，透射，对流和辐射的区域。将所有模型的数值结果与实验进行比较，以将DOM的数值精度与各向异性散射相位函数相关联。结果表明这四种模型方法与实验之间具有良好的相关性。在修改后的模型中，根据模型类型的不同，太阳池由两层玻璃层和一到三个纯水区组成。数值方法包括一种新颖的方法，可以计算所有考虑吸收，发射，散射，透射，对流和辐射的区域。将所有模型的数值结果与实验进行比较，以将DOM的数值精度与各向异性散射相位函数相关联。结果表明这四种模型方法与实验之间具有良好的相关性。将所有模型的数值结果与实验进行比较，以将DOM的数值精度与各向异性散射相位函数相关联。结果表明这四种模型方法与实验之间具有良好的相关性。将所有模型的数值结果与实验进行比较，以将DOM的数值精度与各向异性散射相位函数相关联。结果表明这四种模型方法与实验之间具有良好的相关性。
