Abstract
A flow field aerodynamic analysis using Computational Fluid Dynamics (CFD) model of a single wrap around fin is performed at 0° angle of attack and its flow visualizations are presented in this paper for a subsonic to supersonic Mach range. A comparative study is performed by utilizing two WAF geometries aligned in opposite directions and with different edges (Sharpened and Blunt). The aerodynamic characterization has been conducted using a realizable κ-ϵ turbulence model utilizing a high-quality mesh to understand the nuances of the flow around the curved fin structure. The quantities of interest are the computed aerodynamic coefficients which have been validated with their precursors. By investigating the contours of the pressure coefficient and the relative Mach number, the flow phenomenon in the vicinity of the curved fin can be understood in a finer way.
