Modelling and CFD Simulation of Temperature and Airflow Distribution Inside a Forced Convection Mixed Mode Solar Grain Dryer with a Preheater

In this study, a 3D Computational Fluid Dynamics (CFD) model was developed to simulate the drying process of maize ears cobs in mixed-mode solar grain dryer. The dryer system is aimed operate under forced convection and integrated with preheater heat air prior entering collector. great accuracy using SolidWorks software CFD simulation carried out ANSYS Fluent software. study at analyzing predicting temperature airflow distribution system. conducted different velocities varying from 0.5 m/s 2 for values preheater. Results collector were satisfactory, indicating minimum maximum 59.7 ℃ 70.5 conditions, respectively. variation inside chamber predicted an average 64.1 inlets. indicated high turbulence flow recirculation. This desirable combination that promotes good moisture evaporation during process. proves use computer can allow one clearly gain understanding development, mass transfer process, performance dryers used food industry. approach promote improvements existing processes increase productivity.
