The Interaction Between -Shock Waves and Boundary Layers
The interaction betWeen shock v,aves and boundary layers has important effects in msny problems of high-speed flcv?. This paper has been Written as a guide to the litcraturc On the subject, and as a critical review of the present state of lmc~llcdgo concerning both the underlying physical processes and the practical applications. It rvill be clear to the reader that, although substantisl prcgrc...
متن کاملThermal diffusion shock waves.
The Ludwig-Soret effect or thermal diffusion, which refers to the separation of liquid mixtures in a temperature gradient, is governed by a nonlinear, partial differential equation in space and time. It is shown here that the solution to the nonlinear differential equation for a binary mixture predicts the existence of shock waves completely analogous to fluid shocks and obeys an expression for...
متن کاملTransient granular shock waves and upstream motion on a staircase.
A granular cluster, placed on a staircase setup, is brought into motion by vertical shaking. Molecular dynamics simulations show that the system goes through three phases. After a rapid initial breakdown of the cluster, the particle stream organizes itself in the form of a shock wave moving down the steps of the staircase. As this wave becomes diluted, it transforms into a more symmetric flow, ...
متن کاملReaction-diffusion waves with nonlinear boundary conditions
A reaction-diffusion equation with nonlinear boundary condition is considered in a two-dimensional infinite strip. Existence of waves in the bistable case is proved by the Leray-Schauder method. 1. Formulation of the problem. Reaction-diffusion problems with nonlinear boundary conditions arise in various applications. In physiology, such problems describe in particular development of atheroscle...
متن کاملStability of noncharacteristic boundary layers in the standing-shock limit
We investigate oneand multi-dimensional stability of noncharacteristic boundary layers in the limit approaching a standing planar shock wave Ū(x1), x1 > 0, obtaining necessary conditions of (i) weak stability of the limiting shock, (ii) weak stability of the constant layer u ≡ U− := limz→−∞ Ū(z), and (iii) nonnegativity of a modified Lopatinski determinant similar to that of the inviscid shock ...
