| Popis: | The performance of a modified wick still is investigated theoretically. The still is fed by the rejected warm water from Humidification-Dehumidification (HDH) unit. The performance is investigated also for using the glass film cooling. In addition, the effect of feed water flowing over the wick is considered. The still output yield would be predicted through this study for both day and night times. Results show that during the daytime, the wick still productivity decreases with increasing the flow rate and increases with film cooling. While, during the night time, the productivity increases for both with and without cooling film. The yield of wick still when using the glass film cooling is more than that without film cooling by about 5.3%, 30% for day and night times respectively. Therefore, the productivity of the wick still with and without film cooling is higher than that of conventional basin by 278.4% and 210.2% respectively. |
