CFD Investigation of Solar Air Heaters provided with an artificial roughness of a BOOT Shape in a rectangular duct.

Abstract

This article is based upon the solar air heaters containing an artificial roughnesses of a boot shape represents the overall and complete study of the heat transfer taking place and the fluid flow processes using computational fluid dynamics (CFD). According to the used roughness in this very article we will be observing the total effect of the heat transfer and friction factor also. Now, this way we will come to the conclusion that how the way our project is quite beneficial from others. The boot shape which has been used in this project is having certain dimension which has been designed using ANSYS. We will first use the smooth-duct for the comparison and then further the variation will be done on the shape of our roughness and the parameters used in theroughness(boot) like  angle of attack, pitch distance, height, etc. The Reynolds number will also be varied from 2000 to 18000 and the observation will be done that on which very Reynolds number the best result is being obtained.
