An efficient method for particle-resolved simulations of neutrally buoyant spheres
Manuel Garcia-Villalba, Blanca Fuentes, Jan Dusek +2
We present a simple modification of the direct-forcing immersed boundary method (IBM) proposed by Uhlmann [J. Comput. Phys, 2005] in order to enable it to be applied to particulate…
A single oblate spheroid settling in unbounded ambient fluid: a benchmark for simulations in steady and unsteady wake regimes
Manuel Moriche, Markus Uhlmann, Jan Dušek
We have performed spectral/spectral-element simulations of a single oblate spheroid with small geometrical aspect ratio settling in an unbounded ambient fluid, for a range of Galil…
On the ice-nucleating potential of warm hydrometeors in mixed-phase clouds
Michael Krayer, Agathe Chouippe, Markus Uhlmann +2
The question whether or not the presence of warm hydrometeors in clouds may play a significant role in the nucleation of new ice particles has been debated for several decades. Whi…
Heat and water vapor transfer in the wake of a falling ice sphere and its implication for secondary ice formation in clouds
Agathe Chouippe, Michael Krayer, Markus Uhlmann +3
We perform direct numerical simulations of the settling of an ice sphere in an ambient fluid accounting for heat and mass transfer with the aim of studying in a meteorological cont…
The motion of a single heavy sphere in ambient fluid: a benchmark for interface-resolved particulate flow simulations with significant relative velocities
Markus Uhlmann, Jan Dusek
Detailed data describing the motion of a rigid sphere settling in unperturbed fluid is generated by means of highly-accurate spectral/spectral-element simulations with the purpose…
Compressed low Mach number flows in astrophysics: a nonlinear Newtonian numerical solver
A. Hujeirat, F. -K. Thielemann, J. Dusek +1
Internal flows inside gravitationally stable astrophysical objects, such as the Sun, stars and compact stars are compressed and extremely subsonic. Such low Mach number flows are u…
