Sorted by: Date Added To NTRS in Descending order Prev 1 2 3 4 5 6 7 8 9 Next  Active control of compressible flows on a curved surface Author(s): Maestrello, L.; Bayliss, A.; Parikh, P.; Turkel, E. Abstract: The effect of localized, time periodic surface heating and cooling over a curved surface is studied. This is a mechanism for the active control of unstable disturbances by phase cancellation and reinforcement. It is shown ...

Abstract: A multi-stage Runge-Kutta method is analyzed for solving the Euler equations exterior to an airfoil. Highly subsonic, transonic and supersonic flows are evaluated. Various techniques for accelerating the convergence to a ... NASA Center: Langley Research Center Publication Year: 1984 Added to NTRS: 2004-11-03 Accession Number: 84N29852; Document ID: 19840021783; Report Number: ICASE-84-32, NAS 1.26:172398, NASA-CR-172398 Accuracy of schemes for the Euler equations with non-uniform meshers Author(s): Turkel, E.; Yaniv, S.; Landau, U. Abstract: The effect of nonuniform grids on the solution of the Euler equations is analyzed. A Runge-Kutta type scheme is considered based on a finite volume formuation. It is shown that for arbitrary grids the scheme can be ... NASA Center: Langley Research Center Publication Year: 1986 Added to NTRS: 2004-11-03 Accession Number: 86A19825; Document ID: 19860035087; Report Number: AIAA PAPER 86-0341 Dynamic acoustics for the STAR-100 Author(s): Bayliss, A.; Turkel, E. Abstract: An algorithm is described to compute time dependent acoustic waves in a jet. The method differs from previous methods in that no harmonic time dependence is assumed, thus permitting the study of nonharmonic acoustical ... NASA Center: Langley Research Center Publication Year: 1979 Added to NTRS: 2004-11-03 Accession Number: 80A26671; Document ID: 19800042501 Multidimensional difference schemes with fourth-order accuracy Author(s): Turkel, E.; Abarbanel, S.; Gottlieb, D. Abstract: An explicit finite-difference algorithm is presented for the solution of quasilinear divergence free multidimensional hyperbolic systems. The method consists of four steps per time level. The resulting scheme is fourth-order ...

Abstract: No Abstract Available NASA Center: NASA (non Center Specific) Publication Year: 1982 Added to NTRS: 2004-11-03 Accession Number: 83N76933; Document ID: 19830075926; Report Number: AD-A121211, AFOSR-83-0925TR, NAS 1.26:170367, NASA-CR-170367 Far field conditions for compressible flows Author(s): Bayliss, A.; Turkel, E. Abstract: The numerical treatment of exterior regions requires a method to convert the problem to one in a bounded region. One method is to truncate the unbounded region at some finite, artificial surface. This creates a finite ...

Abstract: The fluctuating field of a jet excited by transient mass injection is simulated numerically. The model is developed by expanding the state vector as a mean state plus a fluctuating state. Nonlinear terms are not neglected ...
