本文研究了在夏季气候条件下，水深对被动式单坡蒸馏系统蒸发传质系数的影响。在夏季气候条件下，对0.04 ~ 0.18m五种不同水深，不同日数，24 h的南向单坡太阳蒸馏器进行了实验。本文的目的是研究内部传热系数的行为变化与水深的蒸馏。应当理解，热传递系数显著地取决于水深。还观察到，夜间蒸馏是显着的，在较高的水深的情况下，因为减少的环境和存储的能量内。
In this communication, an attempt has been made to find out the effect of water depth on evaporative mass transfer coefficient for a passive single-slope distillation system in summer climatic condition. The experiments have been conducted on a south facing, single slope, solar still of 30° inclination of condensing cover, in summer climatic condition for 24 h on different five days for different five water depths from 0.04 m to 0.18 m. The objective of the present paper is to study the behavioral variation in internal heat transfer coefficients with respect to the water depth in the still. It is understood that the heat transfer coefficients depends significantly on water depths. It is also observed that the nocturnal distillation is significant in the case of higher water depths because of reduced ambient and stored energy within it.
