Direct Numerical Simulation of Detonation
AIP Conference Proceedings, 2006The last decade has been witness to a thousand fold gain in computational power, in addition to comparable gains from improved computational algorithms such as adaptive mesh algorithms (AMR). But, even with these gains, there are many detonation phenomena which are beyond the current and foreseeable capabilities of direct simulation of resolved ...

Direct Numerical Simulation of Supersonic Jet Flow
Journal of Engineering Mathematics, 1997A numerical method is given for direct numerical simulation of the nonlinear evolution of instability waves in supersonic round jets, with spatial discretisation based on high-order compact finite differences. We analyse numerical properties of a class of symmetric and asymmetric schemes, and discuss the implementation of the Navier-Stokes equations in

Direct numerical simulations of turbulence with confinement and rotation
Journal of Fluid Mechanics, 1999The goal of this work is to analyse how solid body rotation affects forced turbulence enclosed within solid boundaries, and to compare it to results of the experiment performed by Hopfinger et al. (1982). In order to identify various mechanisms associated with rotation, confinement, and forcing, a numerical pseudo-spectral code is used for ...

DIRECT NUMERICAL SIMULATION OF A TRANSITIONAL RECTANGULAR JET
Proceeding of Second Symposium on Turbulence and Shear Flow Phenomena, 2001Abstract A well-resolved numerical simulation of a Mach 0.5 jet exiting from a rectangular shaped nozzle with an aspect ratio of 5 into a quiescent ambient was performed at a Reynolds number of 2000 based on the narrow side of the nozzle. The transition process was triggered by the most unstable symmetric linear eigenmode of a parallel laminar jet ...

Applications of direct numerical simulations to interfacial problems
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012The fluid mechanics associated with the interface between two fluids, and in particular air and water, is of obvious importance in applications such as remote sensing, and the characterization of the environment. In remote sensing applications interfacial dynamics play a role in determining signatures in the radar, infrared, and visible wavelengths of ...

Cluster computing for direct numerical flow simulation
1996A parallel implementation of a direct numerical flow simulation for confined swirling flow is described. It is demonstrated that cluster computing is a well suited tool to go beyond the limitations of a single workstation.

Direct Numerical Simulation and Large Eddy Simulation
2010This chapter presents important issues that one needs to consider in order to perform direct numerical simulation (DNS) and large eddy simulation (LES) of turbulent flows. We also present important similarities and differences between DNS and LES.
