Determination of the heat transfer coefficient by convection, according to shape of the baffles (solar air collector)

EasyChair Preprint 5999

Abstract

The aim of this experimental study is to find the thermal transfer coefficient by convection in different modes of transversal baffles to the airflow in the solar air collector. The study enabled us to formulate a mathematical equation for the heat transfer coefficient as a function to pressure drop and the mass flow rate, and this mathematical model gave results that are close to the real results in different position of baffles (45°, 90°, 135°, and mixed between 135°and 45°). Through these results, we find that the perfect heat transfer coefficient by convection was in the mode where β = 90° and the mixed-mode, but we noticed that the pressure drop in the mixed-mode was less, this let us say that the best mode for the baffles is the mixed one
