Studying the Effects on the Absorption Rate of Absorber Plate Having Different Surface Shapes

Abstract:

The aim of this study is to provide a remedy for the low absorption rate of absorber plate. This paper presents an experimental investigation and simulation of the optical path on the absorber plate with having different surface shapes. In the study an analysis of three types of absorber plate: a base flat-plate, V shape plate and the sinusoidal-corrugated absorber plate are presented. The results of the experiments were evaluated at the same time of the days. The comparisons of absorption rate of absorber plat were made among them. The present data showed that the absorption rate of the sinusoidal-corrugated absorber plate is the highest.
