NEW CONCEPT FOR IMPROVING SOLAR STILL PERFORMANCE BY USING VIBRATORY HARMONIC EFFECT THEORETICAL ANALYSIS, PART-2

This paper presents the theoretical analysis of a new concept basin type solar still with added helical wires packing layer subjected to a vibratory effect. The improvement of the performance of this basin type solar still is described in details experimentally in part-1, by the author. The thermal modeling have been done by using the imperial relations of the free convection heat transfer in order to correlate the temperature difference of the thermal boundary layer in the basin water depth in both flat bottom and with added helical wire packing layer. The system dynamics is modeled based on the transmissibility equation for evaluating the periodic motions of the helical wired packed layer and the condensing polycarbonate glass cover. The effect of these harmonic motions on the heat transfer coefficient is correlated. The effect due to added helical wired packed layer with and without vibration is compared with the conventional basin type solar still (CSS) and the experimental results obtained in Part1 by the author and come in good agreement. The deviation of the theoretically calculated results is found about +7% and +11.1% at low and high basin water temperatures respectively.
