The exact Riemann solutions are constructed in completely explicit forms for the drift-flux
equations of the one-dimensional inviscid, compressible and isentropic liquid-gas two …

The analytical solutions of the Riemann problem for the isentropic Euler system with the
logarithmic equation of state are derived explicitly for all the five different cases. The …

The exact Riemann solutions are presented in fully explicit forms for the one-dimensional
isentropic Euler system of gas dynamics with the body force, in which the shock and …

The Riemann problem for the one-dimensional zero-pressure gas dynamics system is
considered in the frame of α− solutions based on a solution concept defined in the setting of …

The Riemann problem for a pressureless hydrodynamic model is solved explicitly, whose
solution is either a contact-vacuum-contact wave or a delta shock wave to connect the left …

All the possible Riemann solutions are constructed in fully explicit forms for the one-
dimensional inviscid liquid–gas two-phase isentropic flow model of drift-flux type. The …

In the frame of α− solutions defined in the setting of distributional products, the discontinuous
solutions to the Riemann problem for a nonlinear chromatography system are constructed …

This article studies a Riemann problem for the so-called “p-system” ut− vx= 0, vt−[σ (u)] x= 0,
which rules one-dimensional isentropic thermoelastic media. Such study is made using a …

The Riemann problem for the one-dimensional Eulerian droplet model is solved by
employing Sarrico's theory of distributional products. The discontinuous solutions including …

The present paper concerns the system ut+[ϕ (u)] x= 0, vt+[ψ (u) v] x= 0 having distributions
as initial conditions. Under certain conditions, and supposing ϕ, ψ: ℝ→ ℝ functions, we …
