| Abstract [eng] |
The internal geometrical parameters of the pin-fin arrays have a significant influence on its performance. This paper presents a three-dimensional numerical analysis of pin-fin arrays where only a small part of the channel is modelled by applying cyclic boundary conditions. The simulations are performed using the computational fluid dynamics software OpenFOAM v10. The results are validated against real experimental data and previous two-dimensional study. Furthermore, in order to address the lack of consistent research data on the influence of the pin spacing, this study aims to systematically model and investigate the hydraulic performance of pin-fin array by changing the transverse pitch slightly while keeping the longitudinal pitch, the diameter of the pins, and the height of the channel unchanged. For an inline layout of elliptical pin-fins, it was found that the optimum ratio between the transverse spacing and the width of the pins should be between 1 and 1.5. |
