چکیده

In 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 offers significantly improved computation speed and can be applied to challenging direct numerical simulation (DNS) problems. paper presents several high-resolution cases OpenCFD-SCU: (1) 24° compression ramp at Mach 2.9, where length of is 200 mm mesh number 7.68 × 10 9 ; (2) 34° 6 with 9.3 (3) cold-wall flat plate friction Reynolds 1550 4.5 (4) blunt cone 1 head radius 0° attack angle 10, 24 (5) lifting-body model 11.1 . Compared DNS studies compressible wall-bound turbulent flow under similar conditions, these have larger domains, finer resolutions, or higher numbers, demonstrating capability OpenCFD-SCU broadening scope applications. We conducted preliminary analyses established open-access database store data.

Direct numerical simulation of passive scalar in decaying compressible turbulence

The passive scalars in the decaying compressible turbulence with the initial Reynolds number (defined by Taylor scale and RMS velocity) Re=72, the initial turbulent Mach numbers (defined by RMS velocity and mean sound speed) Mt=0.2-0.9, and the Schmidt numbers of passive scalar Sc=2-10 are numerically simulated by using a 7 order upwind difference scheme and 8 order group velocity control schem...

Direct numerical simulation of turbulence using GPU accelerated supercomputers

Direct numerical simulations of turbulence are optimized for up to 192 graphics processors. The results from two large GPU clusters are compared to the performance of corresponding CPU clusters. A number of important algorithm changes are necessary to access the full computational power of graphics processors and these adaptations are discussed. It is shown that the handling of subdomain commun...

Direct numerical simulation of spiral turbulence

In this paper, we present results of three-dimensional direct numerical simulations of the spiral turbulence phenomenon in a range of moderate Reynolds numbers, in which alternating intertwined helical bands of turbulent and laminar fluids coexist and propagate between two counter-rotating concentric cylinders. We show that the turbulent spiral is comprised of numerous small-scale azimuthally e...

Absolute Permeability Calculation by Direct Numerical Simulation in Porous Media

Simulating fluid flow at micro level is an ongoing problem. Simplified macroscopic flow models like Darcy’s law is unable to estimate fluid dynamic properties of porous media. The digital sample reconstruction by high resolution X-ray computed tomography scanning and fluid-dynamics simulation, together with the increasing power of super-computers, allow to carry out pore-scale simulations throu...

Entropy Splitting for High-Order Numerical Simulation of Compressible Turbulence

A stable high order numerical scheme for direct numerical simulation (DNS) of shock-free compressible turbulence is presented. The method is applicable to general geometries. It contains no upwinding, artificial dissipation, or filtering. Instead the method relies on the stabilizing mechanisms of an appropriate conditioning of the governing equations and the use of compatible spatial difference...
