  1. 16. On Half-Space and Shock-Wave Problems for Discrete Velocity Models of the Boltzmann Equation

    Författare :Niclas Bernhoff; Alexander Bobylev; Giuseppe Toscani; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boltzmann equation; discrete velocity models; boundary value problems; shock waves; MATHEMATICS; MATEMATIK; Matematik; Mathematics;

    Sammanfattning : We study some questions related to general discrete velocity (with arbitrarily number of velocities) models (DVMs) of the Boltzmann equation. In the case of plane stationary problems the typical DVM reduces to a dynamical system (system of ODEs). Properties of such systems are studied in the most general case. LÄS MER
