Abstract

The significance of using a nose cone in aerodynamic applications cannot be overstated, as an appropriately designed nose cone can enhance the performance of the application in terms of drag coefficient and fuel efficiency. In high Mach number environments, even slight alterations in the shape of the nose cone can make a significant impact on the application’s overall performance. Thus, it is necessary to understand the characteristics of the nose cones. In the literature review, arodynamic drag force, Mach number regimes, nose cone designs and the factors affect on nose cone were reviewed. However, existing research has focused on specific type of nose cone design with different speed or various of nose cone designs but with specific speed. Therefore, variations in CFD parameter setups have impacted the accuracy of comparative results. Thus, there is a lack of comprehensive research that investigates the aerodynamic characteristics and fluid flow of various nose cone designs in different Mach number flow regimes. This study focused on the determination of drag coefficient for different nose cone designs at different Mach number regimes through CFD simulation and provide quantitative analysis for selection of nose cone based of different Mach number flow regimes application. In this project, 10 nose cone designs (Power n=0.5, Power n=0.75, Parabolic
