Open-Source Parametric Airfoils to Study Geometric Effects on Buffet
Markus Zauner, David J. Lusher, Pradeep Moise +3
Recent research into buffet in the transonic flow regime has been focused on a limited number of proprietary airfoil geometries and has mainly considered parametric variations in M…
Sensitivities of Free-Air RANS and DDES Methods on the High-Lift NASA CRM
Markus Zauner, Andrea Sansica, Tomoaki Matsuzaki +2
To reduce the time-to-market of future aircraft, it is crucial to predict the flight envelope accurately before building prototypes for flight tests. The High-Lift Prediction Works…
High-fidelity study of three-dimensional turbulent transonic buffet on wide-span infinite wings
David J. Lusher, Andrea Sansica, Markus Zauner +1
Turbulent transonic buffet is an aerodynamic instability causing periodic oscillations of lift/drag in aerospace applications. Involving complex coupling between inviscid and visco…
Effect of Tripping and Domain-Width on Transonic Buffet on Periodic NASA-CRM Airfoils
David J. Lusher, Andrea Sansica, Atsushi Hashimoto
Transonic buffet is an instability characterized by shock-oscillations and separated boundary-layers. High-fidelity simulations have typically been limited to narrow domains to be…
