Embedded direct numerical simulation for aeronautical CFD

A Numerical Framework for the Direct Simulation

Our understanding of solid-fluid dynamics has been severely limited by the nonexistence of a high-fidelity modeling capability for these multiphase systems. Continuum modeling approaches overlook the microscale solid-fluid interactions from which macroscopic system properties emerge, while experimental inquiries have been plagued by high costs and limited resolution. One promising numerical alt...

Temporally regularized direct numerical simulation

Experience with fluid-flow simulation suggests that, in some instances, under-resolved direct numerical simulation (DNS), without a residual-stress model per se but with artificial damping of small scales to account for energy lost in the cascade from resolved to unresolved scales, may be as reliable as simulations based on more complex models of turbulence. One efficient and versatile manner t...

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...

Numerical Simulation of Embedded Non-volatile Memory

Non volatile memories have in recent years become an established component of all electronic systems, especially portable systems. The general trend towards a higher level of integration and speed are pushing towards their integration with complex logic – embedded nonvolatile memory. Non Volatile memory research in the NMRC, which was stimulated by a Marie Curie Fellowship, has focused on the m...
