Abstract

The Solar Still functions through utilizing solar energy for the process of distilling water. Researchers worldwide are investigating techniques to enhance effectiveness and output of solar stills. The present research is aimed to study variations in different parameters measured during the experimentation of solar still and to analyze the variation of temperature and radiation absorption coefficients for varying water depths. It has been noted that with increase in water level, the maximum temperature achieved within the still decreases. The radiation absorption coefficient with higher water levels, 0.0937 m, is 0.53967 m-1 in comparison to other instances with lower water levels, 0.0625 m, 0.0312 m, and 0.0156 m of radiation absorption coefficient 0.53999 m-1, 0.53999 m-1 and 0.53999 m-1 respectively. The experimentation with a hybrid setup of single slope solar still and a Flat Plate Collector (FPC) (MANIT, Bhopal (23.2599° N, 77.4126° E)) has been used to record for 3 consecutive days during sunshine hours for the month of January. The parameters have been analyzed for a comparative study of convective, radiative, and evaporative heat transfer coefficients.

单坡太阳能蒸馏器的实验和 CFD 建模

太阳能蒸馏器的功能是利用太阳能蒸馏水。全世界的研究人员都在研究提高太阳能蒸馏器效率和产量的技术。本研究旨在研究太阳能蒸馏器实验过程中测量到的不同参数的变化，并分析不同水深下温度和辐射吸收系数的变化。我们注意到，随着水位的增加，蒸馏器内达到的最高温度会降低。水位较高时（0.0937 米）的辐射吸收系数为 0.53967 米-1，而水位较低时（0.0625 米、0.0312 米和 0.0156 米）的辐射吸收系数分别为 0.53999 米-1、0.53999 米-1 和 0.53999 米-1。实验使用了单坡太阳能静止器和平板集热器（FPC）混合装置（MANIT，博帕尔（北纬 23.2599°，东经 77.4126°）），连续 3 天记录了 1 月份的日照时间。对参数进行了分析，以便对对流、辐射和蒸发传热系数进行比较研究。

期刊介绍： The Journal of Enhanced Heat Transfer will consider a wide range of scholarly papers related to the subject of "enhanced heat and mass transfer" in natural and forced convection of liquids and gases, boiling, condensation, radiative heat transfer. Areas of interest include: ■Specially configured surface geometries, electric or magnetic fields, and fluid additives - all aimed at enhancing heat transfer rates. Papers may include theoretical modeling, experimental techniques, experimental data, and/or application of enhanced heat transfer technology. ■The general topic of "high performance" heat transfer concepts or systems is also encouraged.
