Digital improvement of the performance of a solar air collector with wavy-shaped baffles

Abstract

In this work, we investigated numerically the thermal and dynamic characteristics of a convective flow in a flat-solar collector with single-pass air. The continuity, momentum, and energy equations govern the flow inside the restricted area between the insulation and the glass. The geometric configuration and the governing equations are solved by the ANSYS FLUENT code, which is based on the finite volume method. The turbulence model (k−𝜀) is used to model the turbulence. This study shows the influence on the performance of the collector using wavy shaped baffles, the impact of temperature and flux heat on its efficiency for different heights and baffles positions.
