Finite Elements for Fluid Dynamics, Mixed-Typed Problems, Transonic Flows

摘要

The report included 4 parts; (1) Transonic and supercritical aerodynamics- remarks on field geometry and descretizations, by N. Geffen. (2) Some open questions in the theory of systems of Conservation laws of mixed type, by M.S. Mock- a continuation of his work reported last year. (3) Further comments and analysis of isoparametric characteristic elements for the Tricomi equation, by S. Yaniv and N. Geffen. (4) Accurate difference schemes for the solution of Tricomi's equation in the hyperbolic region, by D. Levin. The first two parts formulate the problem of mixed transonic flows. (Author)
