Outflow Driven Turbulence in Molecular Clouds
In this paper we explore the relationship between protostellar outflows and turbulence in molecular clouds. Using 3-D numerical simulations we focus on the hydrodynamics of multiple outflows interacting within a parsec scale volume. We explore the extent to which transient outflows injecting directed energy and momentum into a sub-volume of a molecular cloud can be converted into random turbule...
متن کاملCluster Formation in Protostellar Outflow-Driven Turbulence
Most, perhaps all, stars go through a phase of vigorous outflow during formation. We examine, through 3D MHD simulation, the effects of protostellar outflows on cluster formation. We find that the initial turbulence in the clusterforming region is quickly replaced by motions generated by outflows. The protostellar outflow-driven turbulence (“protostellar turbulence” for short) can keep the regi...
متن کاملOutflow Driven Cavities: Numerical Simulations of Intermediaries of Protostellar Turbulence
We investigate the evolution of fossil cavities produced by extinct YSO jets and wide angle outflows. Fossil cavities are ellipsoidal or cylindrical shells of swept-up of ambient (molecular cloud) material moving at low velocities. The cavities form when the momentum in a YSO jet or wide angle outflow decays in time allowing the bowshock or swept-up shell to decelerate to velocities near the tu...
متن کامل5063 : AGN driven outflow of warm and cold gas ⋆
We present new ATCA 17and 24-GHz radio images and ESO-NTT optical spectra of the radioloud Seyfert galaxy IC 5063, the first galaxy in which a fast (∼ 600 km s) outflow of neutral hydrogen was discovered. The new radio data confirm the triple radio structure with a central, unresolved flat-spectrum core and two resolved radio lobes with steep spectral index. This implies that the previously det...
متن کاملInflow/Outflow Boundary Conditions for Particle-Based Blood Flow Simulations: Application to Arterial Bifurcations and Trees
When blood flows through a bifurcation, red blood cells (RBCs) travel into side branches at different hematocrit levels, and it is even possible that all RBCs enter into one branch only, leading to a complete separation of plasma and RBCs. To quantify this phenomenon via particle-based mesoscopic simulations, we developed a general framework for open boundary conditions in multiphase flows that...
