Non-reflecting boundary conditions and tensile instability in smooth particle hydrodynamics [PDF]

, 2012
This thesis aimed at the understanding and further development of smoothed particle hydrodynamics (SPH). The first part described the implementations of non-reflecting boundary conditions for elastic- waves in SPH. The second part contains a stability

Nearly critical superfluids in Keldysh-Schwinger formalism

Journal of High Energy Physics
We examine the effective theory of critical dynamics near superfluid phase transitions in the framework of the Keldysh-Schwinger formalism. We focus on the sector capturing the dynamics of the complex order parameter and the conserved current ...

Finite-element modeling of liquid-crystal hydrodynamics with a variable degree of order [PDF]

, 2006
A finite-element model of liquid-crystal hydrodynamics based on the Qian and Sheng formulation has been developed. This formulation is a generalization of the Ericksen-Leslie theory to include variations in the order parameter, allowing for a proper ...

Pole skipping from universal hydrodynamics of (1+1)d QFTs

Journal of High Energy Physics
(1+1)d QFTs provide a tractable arena for understanding the emergence of hydrodynamics in thermal states. At high temperatures this process is governed by the weak breaking of conformal symmetry, and so in this limit many features of the hydrodynamic ...

Experimental investigation of hydrodynamics of melt layer during laser cutting of steel [PDF]

, 2011
In laser cutting process, understanding of hydrodynamics of melt layer is significant, because it is an important factor which controls the final quality. In this work, we observed hydrodynamics of melt layer on kerf front in the case of laser cutting of

The invariant theory of isotropic turbulence in magneto-hydrodynamics

, 1951
In this paper the invariant theory of isotropic turbulence in magneto-hydrodynamics is developed on the basis of the equations of motion recently derived by Batchelor to describe the hydrodynamics of an incompressible fluid which is also a good ...
