Composite Type, Change of Type, and Degeneracy in First Order Systems with Applications to Viscoela degeneracy. We are interested in these effects with respect to viscoelastic fluid flow and hence we focus on the properties of two particular models of differential type, the Upper Convected Maxwell model and the Bird-DeAguiar model. Friedrichs’ theory of symmetric positive operators is discussed a作者: 夸張 時(shí)間: 2025-3-22 07:53

Admissibility of Solutions to the Riemann Problem for Systems of Mixed Type,alized entropy inequalities. This includes the case of mixed-type shocks (elliptic-hyperbolic). The admissibility condition of transonic small disturbance theory is shown to arise from an additional conservation law different from the one used in the case of the classical .-system in isentropic gas dynamics.作者: LATHE 時(shí)間: 2025-3-29 09:54
Numerical Simulation of Inertial Viscoelastic Flow with Change of Type, of the flow of a Maxwell fluid around a circular cylinder for various flow regimes. We compare creeping flows, Newtonian flows and supercritical viscoelastic flows. We show that the flow kinematics is affected by supercritical flow conditions. In particular, a vorticity shock forms ahead of the cylindrical body.作者: scrutiny 時(shí)間: 2025-3-29 13:24
