Abstract

This work primarily focuses on numerically modelling the damping derivative over the 2D wedge at different pivot points for considerable values of Mach number and incidence angles. The damping derivative is numerically simulated using regression model analysis. The two-dimensional piston theory of Ghosh is applied to obtain the analytical findings. The current study considers the variables Mach number, wedge angle and pivot location.
