Abstract

A new concept of active vibratory solar still is experimentally presented. Firstly, a flexible packed stretched media is installed in the bottom of the basin to increase the efficiency of the still. Secondly, a vibratory harmonic effect is applied. The flexible packed media is formed from stretched helical coiled black coated copper wires, which is considered as a good media for heat absorbing and transferring and as simple thermal storage system. Also, a vibrator (resonator) is installed in the middle of the system structure. The target of using the vibrator is to generate forced vibration to excite the flexible packed media to break the boundary layer and surface tension of the saline water and improve convective beat transfer, and also to excite the condensed polycarbonate glass cover to assist the condensed droplets to slide down before it becomes bigger and possibly falls down in the basin, thus increasing the water vaporization and condensation. The performance is compared with the conventional solar stills (CSS). The vibratory excitation effect is accounted by the new parameter 'vibratory performance gain'. The productivity due to added backed helical wires is found to be 3.4 l/m2 day, with efficiency of about 35 %, and the productivity with vibration is
