We assess in this paper the capability of a pressure correction scheme to compute shock solutions of the homogeneous model for barotropic two-phase flows.
Generally spoken, applying the entropy condition to systems with shock solutions unveils those propagation velocities that ensure that no characteristics rise from discontinuities which would be non-physical.
The new primitive preconditioner can handle both strong and weak shocks, providing highly resolved shock solutions together with correct shock speeds.
Shocks are advanced with Glimm's method which preserves their discontinuous character without any smearing, thus allowing to maintain self-consistency in the shock solutions.
A general property of nonlinear hyperbolic wave equations is the eventual formation of discontinuities (shocks) in the evolving signal and a central issue in shock propagation is the identification of physically acceptable shock solutions.
The numerical results show that the new computational model yields the shock solutions for Mach numbers tested, up to M=30, and removes the singularity near the leading edge of a flat plate that is ill-defined in the case of the Navier Stokes theory.

Roughly speaking, the delta shock solution is a solution such that at least one of the state variables has a Dirac delta function [13].
El-Hanbaly et al. [21] derived the modified KdV Burgers equation in a dusty plasma consisting of Boltzmann-distributed electrons and trapped ions obeying vortex-like distribution and studied the shock solution in a dissipative space plasma.
We attempted to estimate the mass of the source based on the evolution of Quasi-Periodic Oscillation (QPO) frequencies during rising phase modeled with the propagating oscillatory shock solution, and from the correlation of photon index and QPO frequency.
Usually these numerical tools face the shock solution in two ways: 1) a direct mode, by using a time dependent enforcement and by evaluating the time-response and space-response as well as the internal forces; 2) a modal basis approach, by considering a frequency dependent load and of course by evaluating internal forces in the frequency domain.
Detonation/Shock polar analysis on primary triple point structure of abrupt ODW demonstrates that the precursor shock of the ODW near primary triple point is actually a strong shock solution and therefore characterized by local detachment behavior which is responsible for primary triple point's upstream moving.
