Performance analysis and comparison of heat transfer for flat plate and plate with fins by using forced convection in rectangular duct

Given the geographical location, India has enormous scope for usage of solar energy. India is a peculiar to the tropics and due to this here we receive solar radiation all around the year, which is around 3,100 hours of the sunshine which is almost equivalent to the 5,100 trillion kWh. Approximately. This present work deals with the energy as well as energy analysis of solar-air heater which is having absorber flat plate with the forceconvection.
