Riemann problem for a compressible perfect fluid with a constant external force for the Chaplygin gas

Boundary Value Problems, 2018
The Riemann problem for a compressible perfect fluid with a constant external force for the Chaplygin gas is considered. We obtain two kinds of exact solutions. The first one consists of contact discontinuities, while the other one involves a delta shock

Studies of dissipative standing shock waves around black holes [PDF]

, 2009
We investigate the dynamical structure of advective accretion flow around stationary as well as rotating black holes. For a suitable choice of input parameters, such as, accretion rate ($\dot {\cal M}$) and angular momentum ($\lambda$), global accretion ...

The Vanishing Pressure Limit of Riemann Solutions to the Non-Isentropic Euler Equations for Generalized Chaplygin Gas

Advances in Mathematical Physics, 2019
We analyze the appearance of delta shock wave and vacuum state in the vanishing pressure limit of Riemann solutions to the non-isentropic generalized Chaplygin gas equations.

Nonlinear low-frequency wave aspect of foreshock density holes [PDF]

Annales Geophysicae, 2008
Recent observations have uncovered short-duration density holes in the Earth's foreshock region. There is evidence that the formation of density holes involves non-linear growth of fluctuations in the magnetic field and plasma density, which results ...

Four-Quadrant Riemann Problem for a 2 × 2 System Involving Delta Shock

Mathematics, 2021
In this paper, a four-quadrant Riemann problem for a 2×2 system of hyperbolic conservation laws is considered in the case of delta shock appearing at the initial discontinuity.

Probing the neutrino mass hierarchy and the 13-mixing with supernovae [PDF]

, 2003
We consider in details the effects of the 13-mixing (sin^2 theta_{13}) and of the type of mass hierarchy/ordering (sign[ Delta m^2_{13}]) on neutrino signals from the gravitational collapses of stars.

On a Nonsymmetric Keyfitz-Kranzer System of Conservation Laws with Generalized and Modified Chaplygin Gas Pressure Law

Advances in Mathematical Physics, 2013
This paper is devoted to the study of a nonsymmetric Keyfitz-Kranzer system of conservation laws with the generalized and modified Chaplygin gas pressure law, which may admit delta shock waves, a topic of interest.

Vanishing viscosity limit for Riemann solutions to zero-pressure gas dynamics with flux perturbation

Boundary Value Problems, 2018
In this paper, by the viscosity vanishing approach, we consider the Riemann problem for zero-pressure gas dynamics with flux perturbation. The Riemann solutions involve parameterized delta shock wave and constant density state.

Energy partition at the collapse of spherical cavitation bubbles [PDF]

, 2012
Spherically collapsing cavitation bubbles produce a shock wave followed by a rebound bubble. Here we present a systematic investigation of the energy partition between the rebound and the shock.

Histological, antioxidant, apoptotic and transcriptomic responses under cold stress and the mitigation of blue wavelength light of zebrafish eyes

Aquaculture Reports, 2022
As global climate changes, severely temperature variations have significant impacts on survival and development of fish. While the potential effects of light wavelength on cold shock and associated mechanisms remain largely unknown in fish.
