Download or read book Interactions of Tollmien-Schlichting Waves and Dean Vortices. Comparison of Direct Numerical Simulation and a Weakly Nonlinear Theory written by National Aeronautics and Space Adm Nasa and published by Independently Published. This book was released on 2018-12-31 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Direct numerical simulation is used to evaluate a weakly nonlinear theory describing the interaction of Tollmien-Schlichting waves with Dean vortices in curved channel flow. The theory and the simulation agree for certain combinations of parameters, but the two approaches give conflicting results for other combinations. Some possibilities for these discrepancies are discussed. Singer, Bart A. and Zang, Thomas A. Langley Research Center NASA-TP-2919, L-16559, NAS 1.60:2919 RTOP 505-60-01-02...
