ABSTRACT
The aerodynamic characteristics of a blunt cone in multiple flow regimes at Mach number 15 are simulated using a large-scale implicit parallel unified gas kinetic scheme software. A structured grid is used in the physical space and an equally spaced Cartesian grid is used in the velocity space. Every case is computed in parallel with 5100 CPU cores. The Knudsen number based on the radius of blunt cone ranges from 0.00117 to 0.968. The typical flow field characteristics are given, and the contributions of the pressure term and the viscous term to the force coefficients are analyzed.
