Abstract
An investigation of heat transfer between a flow and a horizontal non-circular slender cylinder is presented in this article. Both experimental and numerical approaches are considered here. When using identical cylinders and free-stream velocities, a comparison between experimental data and numerical estimation emphasizes the shear stress transport k–ω turbulent model associated with fine mesh near wall to be appropriate for estimating an average value of heat transfer coefficient in the present configuration. From a numerical parametric investigation, which is based on the latter approach, two formulations of heat transfer are to be considered as thickness does not have a real influence in heat transfer for low Reynolds numbers, whereas for higher values, both thickness and width participate in heat transfer.
