MacCormack Professor Department of Aeronautics and Astronautics, Stanford University   Thu, Oct 9, 2008 2:30 PM   Location: Lopata Hall Room 101   This talk presents a numerical method for solving the Navier-Stokes equations coupled to Maxwell’s equations describing ionized flows within strong electric and magnetic fields. This set is difficult to solve because the characteristic speeds vary from the speed of sound to the speed of light. An algorithm and boundary condition procedures are presented for solving these equations. A scaling of the Maxwell flux vectors is used to control the numerical dissipation inherent in the Modified-Steger-Warming method used to solve the governing equations. This novel scaling procedure enabled both stable and accurate solutions to be found for these equations.  This fully implicit numerical method is tested first on the Hartmann flow problem and then by simulating the flow within an MFD accelerator, generator and simplified scramjet engine (to be presented).     Mechanical, Aerospace & Structural Engineering, Washington University in St. Louis One Brookings Drive, Box 1185, St. Louis, Missouri 63130 Office Location: 305 Jolley Hall, Phone: (314) 935-6047, Fax: (314) 935-4014   Home |  Academics | Research | Department | Resources © 2009 | Did you find it?
