Doppler Tomograms from Hydrodynamical Models of Dwarf Nova Disks
A. J. Gawryszczak, M. Rozyczka
We present three-dimensional models of accretion disks in U Gem - like systems and calculate their Doppler tomograms. The tomograms are based on two different assumptions concernin…
Hydrodynamical Models of Accretion Disks in SU UMa Systems
K. Kornet, M. Rozyczka
We numerically test the mode-coupling model (Lubow 1991a) of tidal instability in SU UMa systems. So far, all numercial models confirming it have been based on SPH codes and isothe…
High-resolution simulations and visualization of protoplanetary disks
P. Ciecielag, T. Plewa, M. Rozyczka
A problem of mass flow in the immediate vicinity of a planet embedded in a protoplanetary disk is studied numerically in two dimensions. Large differences in temporal and spatial s…
CPPA -- a New Hydrodynamical Code for Cosmological Large-Scale Structure Simulations
A. Kudlicki, T. Plewa, M. Rozyczka
We present a new Eulerian code able to follow the evolution of large-scale structures in the Universe in the weakly nonlinear regime. We compare test results with a N-body code and…
Modern Numerical Hydrodynamics and the Evolution of Dense Interstellar Medium
Tomasz Plewa, Michal Rozyczka
We discuss some typical problems related to numerical hydrodynamics of a dense interstellar medium. A newly developed hydrodynamical code based on adaptive mesh refinement techniqu…
