| General note | This study presents a numerical investigation of the flow characteristics around a single and<br/>double-slotted cylinder using computational fluid dynamics (CFD). The simulations were<br/>conducted using CFD software OpenFOAM on a structured grid. The governing equations for<br/>incompressible, laminar flow were solved using the SIMPLE FOAM solver. A mesh-independent<br/>study led to a structured grid with 0.7m cells which was sufficient to capture the flow features<br/>accurately. The results show that the addition of double slits to the cylinder significantly reduces<br/>the drag coefficient as compared to a normal cylinder. The reduction in drag coefficient was<br/>observed to be more significant for wider slits, with a maximum reduction of 22% observed for a<br/>gap between slits and a width-to-diameter ratio of 0.1. The streamlines and pressure contours for<br/>the double-slotted cylinder show a distinct change in the flow pattern due to the presence of the<br/>slits. The flow around the slotted cylinder is observed to be more streamlined with less vortex<br/>shedding as compared to the no-slit cylinder. Additionally, the slits help in reducing the size of the<br/>wake region behind the cylinder, resulting in a reduction of pressure drag. The effect of the<br/>Reynolds number on the flow characteristics was also studied. It was observed that the increase in<br/>Reynolds number resulted in a decrease in drag coefficient for each set of cases, similar to that of<br/>a no-slit and single-slotted cylinder. The results of this study suggest that the presence of double<br/>slits can significantly alter the flow characteristics of a cylinder and improve its aerodynamic<br/>performance, especially in laminar conditions. The findings of this study can have potential<br/>applications in various fields, including aerospace, wind energy, and marine engineering |
