Direct Numerical Simulations of Nucleate Boiling

Volume 10: Heat Transfer, Fluid Flows, and Thermal Systems, Parts A, B, and C, 2008
Direct Numerical Simulations (DNS) of multiphase flows, where all continuum length and time scales are fully resolved have progressed enormously in the last few years. Increases in computer power and new algorithms now make it possible to follow the unsteady motion of several hundred particles (drops, bubbles and solids) for long enough times so that ...

On Direct Numerical Simulation of Turbulent Flows

Applied Mechanics Reviews, 2011
The direct numerical simulation of turbulence (DNS) has become a method of outmost importance for the investigation of turbulence physics, and its relevance is constantly growing due to the increasing popularity of high-performance-computing techniques.

Direct numerical simulation of bifurcating jets

Physics of Fluids, 2000
The mechanisms leading to bifurcating jets are investigated by means of direct numerical simulation. Two distinct types of jets were obtained by applying a bi-modal perturbation at the nozzle. When forcing simultaneously the counter-rotating helical modes (flapping mode) with the same amplitude and the same frequency, the jet splits into two branches ...

Direct Numerical Simulation and Large Eddy Simulation

2010
This 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.

Cutting bubbles using direct numerical simulation

2015
Due to an increase in the oil price, Fischer-Tropsch synthesis, methanol synthesis and other gas-to-liquid processes become increasingly attractive. These gas-liquid-solid processes are mostly performed in bubble slurry columns [Wang et al., 2007, Yang et al., 2007].
