| dc.description.abstract | This study explored the application of Computational Fluid Dynamics (CFD ) in investigating the efficiency and airflow patterns of three different agricultural solar dryers. The dryers analyzed include trapezium, rectangular prism, and triangular prism top shaped designs. The primary objective was to optimize airflow uniformity and temperature distribution, which are critical factors for improving drying efficiency and product quality. CFD simulations were conducted using COMSOL Multiphysics version 6.2, with models based on the Navier-Stokes equations for fluid flow and the energy equation for heat transfer. The results identified the third design, that is, Triangular Prism geometry top shaped, as the most effective dryer design in terms of drying uniformity and efficiency, thus providing valuable insights for improving post-harvest handling and reducing food losses. The study concluded that the trapezium design offers the best performance in terms of uniform drying and energy efficiency. The practical implication of these findings is the potential reduction of post-harvest losses by improving drying technologies in agriculture. The triangular-shaped dryer provides a cleaner, more efficient drying process, promoting food preservation and supporting the sustainability of small-scale farmers in developing regions. This contributes to food security and climate change mitigation by reducing dependence on traditional, fossil-fuel-powered drying methods. | |
