ABSTRACT This work presents the considerations and results of thermofluid characteristics of air flow over an inclined heated flat plate with particular reference to solar collector. The study is motivated by the need to better understanding of heat transfer from the top surface of flat-plate solar energy collectors. The effects of angle of attack, heat flux and Reynolds number are experimentally and numerically investigated. The plate was fixed in the test section with a special mechanism have a capability of changing the angle of attack. A finite volume descretization method using body-fitted coordinates and SIMPLE-based solution algorithm are applied with a segregated solver. The momentum and energy equations were solved by the second order upwind scheme. The fluid flow and heat transfer over the inclined flat plate are treated using k-ε RNG turbulent model. The model results are validated with the experimental results at the same particular conditions. The validated CFD model was extended to obtain the performance of a wide range of angle of attack and flow rate. The local distributions of the velocity, pressure and turbulence with different angle of attack are presented. | ||||
