Solar energy is one of the abundant renewable energy sources for the places like India where, we have more than 300 good sunshine days in a year. Extracting solar energy for the thermal needs has found more domestic and industrial applications like water heating and air heating requirements. The flat plate solar collectors are more popular in India as they require minimum tracking. The solar air heaters can be used for crop drying applications with assured hygiene environment for drying. Use of artificial roughness increases the heat transfer rate in the solar flat plate air heater with consequent effect of increased pressure drop due to friction. The present work based on computational fluid dynamic (CFD) approach intends to find better operating point for enhanced heat utilization at lower pressure drop. The study investigates the effect of the nature of the flow i.e. turbulent or laminar obtained by varying mass flow rate between 0.01-0.2 kg/s. The effect of relative roughness height on the overall performance of the system constitutes the important aspect of the proposed research.
