摘要：
In this communication an attempt has been made to develop the convective mass transfer relation for a double-condensing chamber solar still (DCS) and a single-sloped conventional solar still (CSS) for different operating temperature ranges. Rigorous experimentations were carried out, on both the DCS and CSS during 1996-97. The experimental data have been used to discover C and n in Nu= C (Gr.Pr)(n) by applying linear regression analysis. Based on the results, it is inferred that (1) the order of C and n are the same as proposed by Dunkle [1] for low operating temperature ranges and (2) the value of C and n changes for operating temperatures other than Dunkle's.
