Abstract

Jet flow is a fundamental fluid-dynamics phenomenon that has been extensively studied. This phenomenon plays a crucial role in various industrial applications, including surface cleaning, flow control, and cooling of electronic components. Offset jets offer advantages in flow pattern control by expanding the impingement area and regulating surface pressure distribution. However, the aerodynamic behavior associated with a single offset jet at low offset ratios has not been explored in depth. Therefore, this study aims to investigate the effect of varying offset jet ratios on the aerodynamic characteristics of a single offset jet, focusing on impingement zone formation, pressure distribution, and surface shear behavior. This study uses Computational Fluid Dynamics (CFD) to investigate the effects of variations in jet offset ratio on the flow’s aerodynamic characteristics. This study used a standard k-ε turbulence model with a structured mesh and a Reynolds number of 10,000. The mesh element used was a fine mesh with 200,000 elements and an error percentage of 0.09436%. The results showed that an OR 3 produced the highest Cf value of 0.0047, a stable Cp distribution of 0.218, and the best impingement zone area. Keywords: Computational fluid dynamic, Impinging zone, Offset jet, Offset ratio, Pressure.
