The aim of the present paper is to investigate the concentration and cavitation phenomenon
in the solution of the Riemann problem (RP) to the pressureless isentropic Euler equations …

In this paper, we study the one-dimensional isentropic compressible Euler system for the
Chaplygin gas through Lie symmetry analysis. The one-dimensional optimal subalgebras …

The main motive of this work is to introduce a numerical investigation for the one and
twodimensional (1D/2D) Chaplygin gas model. Namely, we developed the non …

We consider the isothermal Euler model with non-vacuum initial data. We extract the
Riemann invariants of the isothermal Euler model, which admits vital applications. We also …

The present study is concerned with the analytical solution of Riemann problem for
conservation laws of van der Waals gas. By utilizing Rankine–Hugoniot conditions and Lax …

This paper reports the solution to the Non-homogeneous Riemann problem by applying the
approach of differential constraint for the one-dimensional (1− D) generalized Chaplygin gas …

This paper considers the one-dimensional model of heat conduction in solids at low
temperature, the so called phonon-Bose model. The nonlinear model consists of a …

Abstract Gupta et al.(2020) had obtained a nontrivial solution for the Chaplygin gas
equations and the generalized Riemann problem for the Chaplygin gas equations was …

The present study focuses to examine how a plane piston behaves in a generalized
Chaplygin gas when it moves at a constant speed. A methodical perturbation approach is …

In the nonlinear system, the wave is considered to be moving surface along which the flow
variables and their derivatives occupy certain kind of discontinuity that are carried along by …
