Experimental study of desorption and regeneration analysis of cylindrical desiccant layer arrangements

The present study discusses the effects of single-layer and double-layer desiccant bed arrangements on the desorption coefficient and the regeneration capability, at different regenerative temperature differences and Reynolds numbers. Six Reynolds numbers, ranging between 14000 and 69000, and six re...

Description
Summary:The present study discusses the effects of single-layer and double-layer desiccant bed arrangements on the desorption coefficient and the regeneration capability, at different regenerative temperature differences and Reynolds numbers. Six Reynolds numbers, ranging between 14000 and 69000, and six regeneration temperature differences, ranging from 23 °C to 61.6 °C, have been studied and discussed in the present work. According to the results, the desorption coefficient is inversely proportional to the Reynolds number, and directly proportional to the regeneration temperature difference, for both desiccant bed arrangements. The desorption coefficient increased as the regeneration temperature difference increased, for both cases. The regeneration capability at the Reynolds number of 14000 is 10 times higher than that at the Reynolds number of 69000 for the single-layer arrangement. Moreover, for the double-layer arrangement, the regeneration capability at the Reynolds number of 14000 is 8 times higher than at the Reynolds number of 69000. At low Reynolds numbers, the regeneration capacity of the double-layer arrangement is approximately 19 % higher than that of the single-layer arrangement. The recorded data also show that the desorption coefficient increases with increasing heat energy supplied per unit volume. In addition, the regeneration capacity is inversely proportional to the Reynolds number at the Reynolds numbers of 20000 and above.
