CFD Simulation and Analysis of Artificially Roughened Solar Air Heater

Need of energy has become the basic necessity for every developing country in the world. Use of renewable energy plays a superior solution. The threat of extinction of the conventional power sources has paved its way for seeking alternate sources of energy. In the category of renewable, Sun is the ultimate source and utilizing the solar energy in a proper way can eliminate the energy crisis of the world. The main advantages of solar energy are that it is clean, able to operate independently or in conjunction with conventional energy sources, and is remarkably renewable. The main limitations are that it is currently more expensive than traditional energy, and the availability of solar energy is not consistent with time.
