Dynamic Modeling and a Parametric Study of an Indirect Solar Cabinet Dryer

Energy and exergy analysis of an indirect solar cabinet dryer based on mathematical modeling results

“…In this period, the solar radiation is zero but the outflow exergy of the collector has a larger value than that of the inflow exergy. In fact, as can be seen in the experimental study of Mohanraj and Chandrasekar [14] and also in the developed model of Sami et al [1], a solid packing as storage materials was used below the absorber plate, and the stored energy during the day could be transferred to the flowing air through the night. The use of the solar collector with storage materials by Mohanraj and Chandrasekar [14] seems to be a good idea.…”

“…Our previous presented model [1], for performance analysis of a cabinet solar dryer was verified by using the experimental data reported by Dissa et al [15] and Mohanraj and Chandrasekar, [14]. In order to examine the capability of the model, the calculated values of the different parameters were compared with the corresponding experimental ones.…”

“…The model results showed a good agreement with the mentioned experimental data. The details of this verification process could be found in Sami et al [1], and only a brief discussion of more important results comes below. Fig.…”

“…As an extension to our previous work [1], the energy and exergy analysis of an indirect cabinet solar dryer will be addressed in the present study. A new approach is illustrated for achieving the scope of work, which is using the mathematical modeling as a useful technique for energy and exergy analysis and also for determining microscopic exergy destruction characteristics of such equipment.…”

“…Governing equations for the drying chamber can also be found in Table 1. More details for model assumptions, supplementary equations, required nomenclature and derivation of the equations can be found in Sami et al [1].…”
