CFD ANALYSIS OF SOLAR AIR HEATER OF V SHAPE RIBS AT CONSTANT PITCH

The effective use of a solar duct is limited at its maximum operational junction temperature. The study was conducted by using the Computational Fluid Dynamics (CFD) method. The Ducts are used with flow of air with temperature such as power houses, malls and industrial applications. The major study was done on artificially roughened semicircular shaped V-Ribs with different relative gap widths. The heat transfer media was taken as an air & Aluminum (Al) as Duct material. In our analysis, CFD was used and the model was developed on CREO 5.0. In order to verify the present CFD model, the Nusselt number and the Friction factor are compared with the available experimental results present in the literature. And the design of semicircular shaped V-Ribs with different relative gap widths having gap width of 1.5mm, 2.5mm, 3.5mm, 4.5mm, 5.5mm on roughness. In this study, the simulations of semicircular shaped ribs of roughness at constant wind velocity i.e., 6.5 m/s and the configurations of duct design are proposed. The Experimental result is done by carrying out the simulation work on the ANSYS Fluent 15.0 Work bench.
