Energy is a crucial input in the process of economic, social and industrial development of any nation. During past several decades, energy demand of the world has been increasing continuously at an alarming rate due to increase in population, industrialization, transportation etc. Continuous use of fossil fuels have resulted energy crisis and environment degradation at global level. On the many alternatives, solar energy is an important renewable energy resource that has the potential of fulfilling all energy needs. Some important applications of solar energy are solar water heating, solar space heating/cooling, solar cooking, solar crop drying, solar power generation etc. Simplest method to utilize solar radiation is to convert it into thermal energy for heating applications by using solar collectors. Solar air Dryer because of their inherent simplicity are cheap and are used for many domestic and commercial applications like space heating, crop drying, wood seasoning etc. In this paper the objective of the CFD flow study is to design, test and optimize flow-conditioning devices, as appropriate, to guide the gas flow through the duct. In this a two-dimensional numerical simulation of the heat transfer, Nussult number, Velocity and temperature was conducted using the CFD code FLUENT VERSION 14.5. The CFD modeling involves numerical solutions of the conservation equations for mass, momentum and energy. These three equations are used to model the convective heat transfer process with the following assumptions; (a)The flow is steady, fully developed, turbulent and two dimensional. (b) Incompressible fluid and flow.(c) The duct wall, absorber plate and roughness material are homogeneous and isotropic.
