Heat Transfer Enhancement and efficiency optimization of Novel Polygonal Collector Influence of Thermophysics Characteristic of Nanoparticles Using Response Surface Methodology

Abstract

The novelty of present study is the improvement of thermal efficiency and energy management for novel polygonal collector, composed of chaotic TiO2 and LiBr nanoparticles. The optimization process of thermal efficiency is considered using response surface methodology. So, total temperature of octagonal collector influence of TiO2 Nano particles is 63.27% and 24.32% more than triangular and cubical collectors. Also, incident radiation of octagonal collector influence of TiO2 Nano particles is 3.56% and 4.52% more than triangular and cubical collectors. Moreover, the surface radiation absorption of the octagonal collector influence of LiBr Nano particles is 2.93% and 4.67% more than the triangular and cubical collectors. Moreover, the total ground heat flux of the octagonal collector influence of LiBr Nano particles is 74.26% and 74.63% more than the triangular and cubical collectors.
