Аннотация
This study presents a comprehensive comparative analysis of four OpenFOAM solvers for simulating supersonic flow around a Spherically Blunted Cone. Utilizing the generalized computational experiment technique, we evaluated solver performance across varying Mach numbers and cone half-angles. The research aimed to provide clear recommendations for solver selection in high-speed flow simulations. Results show that rhoCentralFoam exhibited the lowest deviation from the exact solution, followed closely by pisoCentralFoam. The sonicFoam solver demonstrated limitations at higher Mach numbers. The QGDFoam solver, while showing promise, requires further optimization of its smoothing parameter for improved accuracy. This study offers valuable insights for OpenFOAM users, enabling them to make informed decisions when choosing solvers for compressible gas dynamics problems.
