Numerical Simulation of a Compact Indirect Solar Dryer

Abstract

This study focuses on the analysis of the thermo-dynamic behavior of a compact indirect solar dryer. The objective is to characterize the heat transfer phenomena occurring within the system, with particular emphasis on the mechanisms of forced and natural convection, as well as the temperature distribution within the different components of the dryer. The studied device is based on a thermal solar collector coupled with an insulated drying chamber, allowing heat transfer through a flow of heated air without direct exposure of the product to solar radiation. A numerical simulation approach, possibly supported by experimental data, is considered in order to evaluate the energy efficiency of the system and optimize its operating parameters.
