Abstract Solar still water production enhancement was measured in experimental single-slope basin-type solar stills (BTSS) by perturbing the water surface of the still. The perturbation is achieved by the injection of air bubbles into the water basin, which produces surface ripples, thus increasing the overall evaporative surface area and stimulating the mass transfer coefficient. Overall, distilled water production is therefore enhanced as the evaporation improves. The position and flowrate of the air bubble injectors do not seem to affect the amount of evaporation increase. Two very low-tilt covered, shallow BTSS were operated simultaneously side by side. Only one of them was subjected to mass transfer enhancement, in order to produce conclusive mass transfer enhancement results. These results can be accommodated in a computer simulation program with the introduction of a simple intensification factor. Experimental work was carried out in the semi-desert, water-starved, highly insolated region of La Paz, BCS, Mexico.

通过水面扰动增强太阳能蒸馏

摘要 在实验性单斜盆式太阳能蒸馏器 (BTSS) 中，通过扰动蒸馏器的水面，测量了太阳能蒸馏器产水量的增加。扰动是通过向水盆中注入气泡来实现的，气泡会产生表面波纹，从而增加整体蒸发表面积并刺激传质系数。总体而言，随着蒸发的改善，蒸馏水的产量因此得到提高。气泡喷射器的位置和流量似乎不影响蒸发量的增加。两个倾斜度非常低的浅层 BTSS 同时并排运行。只有其中之一进行了传质增强，以产生确凿的传质增强结果。通过引入一个简单的增强因子，这些结果可以包含在计算机模拟程序中。实验工作在墨西哥 BCS 拉巴斯的半沙漠、缺水、高度日晒的地区进行。
