AbstractIn the author's previous work, we introduced an open-source accelerated computational fluid dynamics code for scientific computations using a graphics processing unit system (OpenCFD-SCU). This code offers significantly improved computation speed and can be applied to challenging direct numerical simulation (DNS) problems. This paper presents several high-resolution cases using OpenCFD-SCU: (1) a 24? compression ramp at Mach 2.9, where the length of the ramp is 200 mm and the mesh number is 7.68 x 109; (2) a 34? compression ramp at Mach 6 with a mesh number of 9.3 x 109; (3) a cold-wall flat plate at Mach 10 with a friction Reynolds number of 1550 and mesh number of 4.5 x 109; (4) a blunt cone with a 1 mm head radius and 0? attack angle at Mach 10, where the mesh number is 24 x 109; and (5) a lifting-body model at Mach 6 with a mesh number of 11.1 x 109. Compared with DNS studies of compressible wall-bound turbulent flow under similar conditions, these cases have larger computational domains, finer resolutions, or higher Reynolds numbers, demonstrating the simulation capability of OpenCFD-SCU and broadening the scope of DNS applications. We have conducted preliminary analyses of these cases and have established an open-access database to store these data. The source code of OpenCFD-SCU can be accessed at http://developer.hpccube.com/codes/danggl/opencfd-scu.git; this website also contains detailed database descriptions and data acquisition methods.
