Influence of striped surface with different emissivity on natural convective boundary layer

Abstract

The hypothesis that zebra stripes help generate convection and contribute to thermoregulation remains unclear. In this study, we numerically investigate how stripes affect the natural convection field. A 3D cavity model with a striped surface of varying emissivity was constructed using OpenFOAM. The behavior of convection and changes in the temperature boundary layer were evaluated with and without the stripe pattern by evaluating the temperature and velocity vector distribution.
