Experimental Simulation of Solar Aqua Lens Concentrator

Abstract

The lens was built from readily available materials in the market. The liquid used in lenses were tap water, 30% sugar solution in the hyper elastic low density polyethylene foil. The experimental set up was exposed to sunlight. The focal length point and light intensities were measured at that focal point spot, concentration ratio at each focal point was calculated. The concentration ratio is inversely proportional to focal point. The experimental data was tabulated. The theoretical lens radius of curvature and deformation of lens was validated by ANSYS finite Element Modeling (FEM).The lens deformation of hyper elastic foil was also compare with AUTO CAD. Solar aqua concentrator can be used where high focusing thermal application is required.
