Nonequilibrium thermodynamics of surfaces captures the energy conversions in a shockwave
Bjørn Hafskjold, Dick Bedeaux, Signe Kjelstrup +1
The local entropy production in a shock wave was analysed in the framework of non-equilibrium thermodynamics (NET) of surfaces. We show that the thermodynamic state variables in th…
A consistent reduction of the two-layer shallow-water equations to an accurate one-layer spreading model
Eirik Holm Fyhn, Karl Yngve Lervåg, Åsmund Ervik +1
The gravity-driven spreading of one fluid in contact with another fluid is of key importance to a range of topics. To describe these phenomena, the two-layer shallow-water equation…
Convergence properties of detonation simulations
Chengeng Qian, Cheng Wang, JianNan Liu +3
We present a high-resolution convergence study of detonation initiated by a temperature gradient in a stoichiometric hydrogen-oxygen mixture using the Pencil Code and compare with…
Varying the forcing scale in low Prandtl number dynamos
A. Brandenburg, N. E. L. Haugen, Xiang-Yu Li +1
Small-scale dynamos are expected to operate in all astrophysical fluids that are turbulent and electrically conducting, for example the interstellar medium, stellar interiors, and…
High-order overset grid method for detecting particle impaction on a cylinder in a cross flow
J. R. Aarnes, N. E. L. Haugen, H. I. Andersson
An overset grid method was used to investigate the interaction between a particle-laden flow and a circular cylinder. The overset grid method was implemented in the Pencil Code , a…
Multipoint Radiation Induced Ignition of Dust Explosions: Turbulent Clustering of Particles and Increased Transparency
M. Liberman, N. Kleeorin, I. Rogachevskii +1
It is known that unconfined dust explosions consist of a relatively weak primary (turbulent) deflagrations followed by a devastating secondary explosion. The secondary explosion ma…
Mechanism of unconfined dust explosions: turbulent clustering and radiation-induced ignition
M. Liberman, N. Kleeorin, I. Rogachevskii +1
It is known that unconfined dust explosions typically starts off with a relatively weak primary flame followed by a severe secondary explosion. We show that clustering of dust part…
Eulerian and modified Lagrangian approaches to multi-dimensional condensation and collection
Xiang-Yu Li, A. Brandenburg, N. E. L. Haugen +1
Turbulence is argued to play a crucial role in cloud droplet growth. The combined problem of turbulence and cloud droplet growth is numerically challenging. Here, an Eulerian schem…
Turbophoresis in forced inhomogeneous turbulence
Dhrubaditya Mitra, Nils Erland L. Haugen, Igor Rogachevskii
We show, by direct numerical simulations, that heavy inertial particles (characterized by Stokes number $\St$) in inhomogeneously forced statistically stationary isothermal turbule…
Non-linear simulations of combustion instabilities with a quasi-1D Navier-Stokes code
Nils Erland L. Haugen, Øyvind Langørgen, Sigurd Sannan
As lean premixed combustion systems are more susceptible to combustion instabilities than non-premixed systems, there is an increasing demand for improved numerical design tools th…
