Relativistic hydrodynamics – causality and stability [PDF]

The European Physical Journal Special Topics, 2008
Causality and stability in relativistic dissipative hydrodynamics are important conceptual issues. We argue that causality is not restricted to hyperbolic set of differential equations. E.g. heat conduction equation can be causal considering the physical validity of the theory.

Hydrodynamic capabilities of an SPH code incorporating an artificial conductivity term with a gravity-based signal velocity [PDF]

, 2012
This paper investigates the hydrodynamic performances of an SPH code incorporating an artificial heat conductivity term in which the adopted signal velocity is applicable when gravity is present.

Destabilization of a laminar flow in a rectangular channel by transversely-oriented wall corrugation

Archives of Mechanics, 2011
Linear stability of the flow through the transversely corrugated channel with flat sidewalls is investigated numerically. Two variants of the wall corrugation are considered: symmetric sinusoidal waviness of the top and bottom walls and onesided ...

Dielectrophoretic force-driven convection in annular geometry under Earth's gravity

, 2020
Context: A radial temperature gradient together with an inhomogeneous radial electric field gradient is applied to a dielectric fluid confined in a vertical cylindrical annulus inducing thermal electro-hydrodynamic convection.

Three-dimensional stability of the solar tachocline [PDF]

, 2005
The three-dimensional, hydrodynamic stability of the solar tachocline is investigated based on a rotation profile as a function of both latitude and radius.

Asymptotic boundary conditions for the analysis of hydrodynamic stability of flows in regions with open boundaries

Russian Journal of Numerical Analysis and Mathematical Modelling, 2019
A new approach to formulation of asymptotic boundary conditions for eigenvalue problems arising in numerical analysis of hydrodynamic stability of such shear flows as boundary layers, separations, jets, wakes, characterized by almost constant velocity of

Hydrodynamic instability in warped astrophysical discs [PDF]

, 2013
Warped astrophysical discs are usually treated as laminar viscous flows, which have anomalous properties when the disc is nearly Keplerian and the viscosity is small: fast horizontal shearing motions and large torques are generated, which cause the warp ...

Changes in the Hydrodynamic Characteristics of Ships During Port Maneuvers

한국해양공학회지, 2022
To reach a port, a ship must pass through a shallow water zone where seabed effects alter the hydrodynamics acting on the ship. This study examined the maneuvering characteristics of an autonomous surface ship at 3-DOF (Degree of freedom) motion in deep ...

Stability properties of the collective stationary motion of self-propelling particles with conservative kinematic constraints [PDF]

, 2006
In our previous papers we proposed a continuum model for the dynamics of the systems of self-propelling particles with conservative kinematic constraints on the velocities. We have determined a class of stationary solutions of this hydrodynamic model and
