A Review on Computational Fluid Dynamics Analysis on Greenhouse Dryer

Abstract

Over the decades Solar energy has been utilizing for the conservation of various agricultural products at different zones in the world. Existing literature reveals that open dehydrating is the mostly followed for the desired application and its efficiency limited to certain extent. In order to overcome the limitations, solar dehydrating is proposed and implemented by various researchers. Greenhouse dryer found to be most appropriate technique to preserve different kinds of fruits, vegetables and grain products. In recent years, a great deal of research has been focused to enhance the performance of the selected method. Traditionally it is confined to empirical form and later it is extended to CFD analysis to obtain effective results through simulations. The present article presents the extensive survey over empirical and CFD analysis of Green house dryer application on dehydrating in both active and passive mode of convections.
