This paper presents the development and implementation of the OpenFOAM library for far-field sonic boom prediction using quasi-linear Whitham theory. The proposed numerical algorithm differs in the order of application of the area balancing rule, which makes the algorithm easier to implement and debug. The numerical simulations of the Seeb-ALR, \(69^\circ \) -delta wing and c25d aircraft models presented in the first and second sonic boom workshops are performed. The supersonic flow solvers rhoCentralFoam and dbnsFoam from the OpenFOAM software are used to obtain the near-field pressure signatures. To validate the developed library, the far-field pressure is calculated with the OpenFOAM simulation data. The results show good agreement with the experimental data and the simulation results of the workshop participants.

摘要

This paper presents the development and implementation of the OpenFOAM library for far-field sonic boom prediction using quasi-linear Whitham theory. The proposed numerical algorithm differs in the order of application of the area balancing rule, which makes the algorithm easier to implement and debug. The numerical simulations of the Seeb-ALR, \(69^\circ \) -delta wing and c25d aircraft models presented in the first and second sonic boom workshops are performed. The supersonic flow solvers rhoCentralFoam and dbnsFoam from the OpenFOAM software are used to obtain the near-field pressure signatures. To validate the developed library, the far-field pressure is calculated with the OpenFOAM simulation data. The results show good agreement with the experimental data and the simulation results of the workshop participants.
