Abstract

There are the selection of roughness geometry has to be based on the parameter that both Thermo-hydraulic Performance of Solar air collector. Number of roughness elements has been investigated on heat transfer & friction characteristics of solar air collectors. In this paper, reviews of various artificial roughness elements used as heat transfer techniques, and improve Thermo-hydraulic performance of solar air collectors is reviewed by using CFD .There are the various results for heat transfer & friction factor for solar air collector by taking different roughness geometries are given & these correlations are predict the Thermo-hydraulic performance of solar air collector having roughened ducts. The aim of this paper is also the awareness of effect of various types’ roughness geometries on heat transfer & friction characteristics of solar air collectors with use of CFD in simplified form.
