TI  - Sonic Boom Prediction Code Development and Sonic Boom Predictions via Open-Source CFD Software
AB  - In this work, a sonic boom prediction code is developed in order to numerically solve the Augmented Burgers' equation using the operator-splitting approach. The developed code was tested using the near-field pressure data for the “NASA Concept 25D with Flow Through Nacelle (C25D)” geometry and was validated by comparing with the sonic boom predictions obtained from two well-known codes; sBoom and bBoom. A mid-solver approach, which utilizes the open-source CFD software OpenFOAM® and a “Mach-cone aligned” structured mesh, was applied to extrapolate the nearfield pressure data to mid-field. Here, the near-field effects were propagated to mid-field by solving the Euler equations. The Mach-cone aligned mesh used in the solutions does not contain an airplane geometry and it was constructed using the open-source mesh generation software Gmsh in an automated manner. Here the user specifies the radii of the inner and outer surfaces, mesh spacing along with streamwise and circumferential directions and flow Mach number, only. Tests were conducted using the near-field data obtained from an inviscid flow solution for the C25D geometry via the open-source CFD software SU2. These tests showed that the mid-solver approach used in this study can successfully propagate near-field data to mid-field regions.
