This paper discusses ongoing work on an all-Mach number, non–dissipative algorithm to solve compressible flows on unstructured grids. The algorithm is capable of handling unstructured grids, which allow efficient and speedy generation of computational meshes for complex geometries. The novel feature of the algorithm is an incompressible scaling for pressure that naturally yields the divergence–...
Several high speed TCP variants are adopted by end users and therefore, heterogeneous congestion control has become the characteristic of newly emerging high-speed networks. In this demonstration, we show the fairness among heterogeneous TCP flows over CRON, a 10Gbps high-speed networking testbed. The significant throughput difference among heterogeneous TCP flows shows that heterogeneous TCP f...
Turbulence modeling has the potential to revolutionize high-speed vehicle design by serving as a co-equal partner costly and challenging ground flight testing. However, fundamental assumptions that make turbulence such an appealing alternative its scale-resolved counterparts also degrade accuracy for practical configurations, especially when fully 3D flows are considered. The current investigat...
The potential application of aggregates of nanoparticles for high-speed flow diagnostics is investigated. Aluminum nanoparticles around 10 nm in diameter are produced by spark discharge in argon gas. Through rapid coagulation and oxidation, aggregates of small effective density are formed. They are characterized by microscopy and their aerodynamics and optical properties are theoretically evalu...
We present an improved lattice Boltzmann model for high-speed compressible flows. The model is composed of a discrete-velocity model by Kataoka and Tsutahara [Phys. Rev. E 69, 056702 (2004)] and an appropriate finite-difference scheme combined with an additional dissipation term. With the dissipation term parameters in the model can be flexibly chosen so that the von Neumann stability condition...
Within the framework of the Local Extremum Diminishing (LED) or Essentially Local Extremum Diminishing (ELED) principle, efficient approaches to obtain a class of non-oscillatory high resolution schemes are presented. The LED principle requires that local maxima should not increase and local minima should not decrease to produce a monotonicity preserving scheme for scalar hyperbolic conservatio...
