Computational model analysis on symmetrical aerofoil shaped pin fin arrays

Abstract

It is a computational model analysis on symmetrical aerofoil pin-fin arrays. The commercial ANSYS 2021 R2 computational tool has been utilized. There are four models prepared on symmetrical aerofoil pin-fin arrays. These four models are no perforated inline aerofoil pin-fin array, perforated inline aerofoil array, no perforated staggered aerofoil array and perforated staggered aerofoil array. The basic geometry, meshing and computational analysis has been created in the Workbench, ICEM and Fluent Discover tool, respectively. In the Fluent solver settings, the k-omega turbulent model has been selected. The Reynolds number implied from 5,000 to 50,000 with an incremental value of 5,000. Moreover, the temperature valve input from 27 to 350℃. The results show that at rising input airflow velocity increases Nusselt number. Out of all the four models the convective heat transfer rate in the perforated one is quite higher than no perforated one. In the staggered perforated aerofoil pin-fin obviously there is more material savings. Apart from that in the no perforated staggered aerofoil pin-fin the pressure drop is lesser and better streamline pressure drop maintained. As far as overall performance is concern the perforated staggered aerofoil pin-fin arrangement gives very promising results.
