Collision fluctuations of lucky droplets with superdroplets
Xiang-Yu Li, Bernhard Mehlig, Gunilla Svensson +2
It was previously shown that the superdroplet algorithm for modeling the collision-coalescence process can faithfully represent mean droplet growth in turbulent clouds. But an open…
Adaptive multiscale methods for 3D streamer discharges in air
Robert Marskar
We discuss spatially and temporally adaptive implicit-explicit (IMEX) methods for parallel simulations of three-dimensional fluid streamer discharges in atmospheric air. We examine…
An adaptive Cartesian embedded boundary approach for fluid simulations of two- and three-dimensional low temperature plasma filaments in complex geometries
Robert Marskar
We review a scalable two- and three-dimensional computer code for low-temperature plasma simulations in multi-material complex geometries. Our approach is based on embedded boundar…
Condensational and collisional growth of cloud droplets in a turbulent environment
Xiang-Yu Li, Axel Brandenburg, Gunilla Svensson +3
We investigate the effect of turbulence on the combined condensational and collisional growth of cloud droplets by means of high resolution direct numerical simulations of turbulen…
Treatment of solid objects in the Pencil Code using an immersed boundary method and overset grids
Jørgen R. Aarnes, Tai Jin, Chaoli Mao +3
Two methods for solid body representation in flow simulations available in the Pencil Code are the immersed boundary method and overset grids. These methods are quite different in…
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…
Cloud-droplet growth due to supersaturation fluctuations in stratiform clouds
Xiang-Yu Li, Gunilla Svensson, Axel Brandenburg +1
Condensational growth of cloud droplets due to supersaturation fluctuations is investigated by solving the hydrodynamic and thermodynamic equations using direct numerical simulatio…
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…
Simulation model for the propagation of second mode streamers in dielectric liquids using the Townsend--Meek criterion
I. Madshaven, P. -O. Åstrand, O. L. Hestad +3
A simulation model for second mode positive streamers in dielectric liquids is presented. Initiation and propagation is modeled by an electron-avalanche mechanism and the Townsend-…
