Computation of Fluid Flows in Non-inertial Contracting, Expanding, and Rotating Reference Frames
A. Y. Poludnenko, A. M. Khokhlov
We present the method for computation of fluid flows that are characterized by the large degree of expansion/contraction and in which the fluid velocity is dominated by the bulk co…
Evolution and Fragmentation of Wide-Angle Wind Driven Molecular Outflows
Andrew Cunningham, Adam Frank, Peggy Varnière +3
We present two dimensional cylindrically symmetric hydrodynamic simulations and synthetic emission maps of a stellar wind propagating into an infalling, rotating environment. The r…
Clumpy Flows in Protoplanetary and Planetary Nebulae
A. Y. Poludnenko, A. Frank, S. Mitran
Many astrophysical flows occur in inhomogeneous media. We briefly discuss some general properties of the adiabatic and radiative inhomogeneous systems and discuss the relevance of…
Strings in the Eta Carinae Nebula: Hypersonic Radiative Cosmic Bullets
A. Y. Poludnenko, A. Frank, S. Mitran
We present the results of a numerical study focusing on the propagation of a hypersonic bullet subject to radiative cooling. Our goal is to explore the feasibility of such a model…
A Laboratory Investigation of Supersonic Clumpy Flows: Experimental Design and Theoretical Analysis
A. Y. Poludnenko, K. K. Dannenberg, R. P. Drake +5
We present a design for high energy density laboratory experiments studying the interaction of hypersonic shocks with a large number of inhomogeneities. These ``clumpy'' flows are…
Formation of Turbulent Cones in Accretion Disk Outflows and Application to Broad Line Regions of Active Galactic Nuclei
A. Y. Poludnenko, E. G. Blackman, A. Frank
We consider the stability of an accretion disk wind to cloud formation when subject to a central radiation force. For a vertical launch velocity profile that is Keplerian or flatte…
