Application to pedestrian flow modeling. On postshock oscillations due to shock capturing schemes in unsteady flow. These follow the "strong-shock" solutions of the analytic equations, meaning that for some oblique shocks very close to the deflection angle limit, the downstream Mach number is subsonic.

It would also be highly desirable to have the numerical methods to be flexible for complicated geometry and boundary conditions, and to be easy in an adaptive and massively parallel environment.

Recent progress in the field has greatly enhanced the original theory and stimulated interesting and critical gas dynamic phenomena and problems.
An infinitesimal curvature effect is also discussed, with a long-standing problem of the bifurcation of the plane Couette flow worked out as an example. In order to deal with correct dynamic of shock waves propagating through multiphase mixtures, the artificial heat exchange method of Petitpas et al.

Some common features of these flow structures and shock waves and the insufficient aspects of numerical and experimental tools lead to two important problems in practices: 1 some shock waves can not be detected or their positions are detected wrong, 2 some flow structures which are not shock waves are wrongly detected to be shock waves.

On postshock oscillations due to shock capturing schemes in unsteady flow.
This work systematizes methods for overcoming the difficulties inherent in the solution of hyperbolic systems. Furthermore, we are interested in the long time solutions of such equations with waves traveling a long distance, such as the electromagnetic waves.These are a set of class notes for a gas dynamics/viscous ﬂow course taught to juniors in Aerospace Engineering at the University of Notre Dame during the mid s.
The course builds upon foundations laid in an earlier course where the emphasis was on subsonic ideal ﬂows. According to Eq. (21), the gas permeability change is directly affected by the gas viscosity and core deformation (i.e., length and cross-sectional area variations), which is consistent with the latest theory accounting for the gas permeability change .First, with the pressure decrease, increased effective stress and matrix shrinkage occur in coal, causing coal deformation accompanied with.
