Hydrodynamic simulations of the triaxial bulge of M31
The interstellar gas flow in the inner disk of M31 is modelled using a new, two dimensional, grid based, hydrodynamics code. The potential of the stellar bulge is derived from its surface brightness profile. The bulge is assumed to be triaxial and rotating in the same plane as the disk in order to explain the twisted nature of M31’s central isophotes and the non circular gas velocities in the i...
متن کاملHydrodynamic stability without eigenvalues.
Fluid flows that are smooth at low speeds become unstable and then turbulent at higher speeds. This phenomenon has traditionally been investigated by linearizing the equations of flow and testing for unstable eigenvalues of the linearized problem, but the results of such investigations agree poorly in many cases with experiments. Nevertheless, linear effects play a central role in hydrodynamic ...
متن کاملDeformation of DNA molecules by hydrodynamic focusing
The motion of a DNA molecule in a solvent flow reflects the deformation of a nano/microscale flexible mass–spring structure by the forces exerted by the fluid molecules. The dynamics of individual molecules can reveal both fundamental properties of the DNA and basic understanding of the complex rheological properties of long-chain molecules. In this study, we report the dynamics of isolated DNA...
متن کاملMeasuring Plastic Deformation
This article describes the current level of understanding of dislocation plasticity in thin films and small structures in which the film or structure dimension plays an important role. Experimental observations of the deformation behavior of thin films, including mechanical testing as well as electron microscopy studies, will be discussed in light of theoretical models and dislocation simulatio...
متن کاملCharacterization of Hydrodynamic Strange
The onset of chaotic motion in hydrodynamic systems is still not well understood. However, significant progress has been made in the past ten years. The evidence indicates that certain fluid systems generate chaotic motion through the nonlinear interaction of a small number of degrees of freedom. Examples include Couette-Taylor flow, Rayleigh-B~nard convection in restricted geometries, and vert...
