Scale-resolving simulations and data-driven modal analysis of turbulent transonic buffet cells on infinite swept wings
David J. Lusher, Andrea Sansica
Transonic buffet is a class of shock-wave/boundary-layer interaction known to exhibit self-sustained two-dimensional (2D) chordwise shock wave oscillations (Strouhal number St=0.05…
Reduced and mixed precision turbulent flow simulations using explicit finite difference schemes
Bálint Siklósi, Pushpender K. Sharma, David J. Lusher +2
The use of reduced and mixed precision computing has gained increasing attention in high-performance computing (HPC) as a means to improve computational efficiency, particularly on…
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…
Direct numerical simulations of shocklet-containing turbulent channel counter-flows
Arash Hamzehloo, David J. Lusher, Sylvain Laizet +1
Counter-flow or counter-current configurations can maintain high turbulence intensities and exhibit a significant level of mixing. We have previously introduced a wall-bounded coun…
OpenSBLI: Automated code-generation for heterogeneous computing architectures applied to compressible fluid dynamics on structured grids
David J. Lusher, Satya P. Jammy, Neil D. Sandham
OpenSBLI is an open-source code-generation system for compressible fluid dynamics (CFD) on heterogeneous computing architectures. Written in Python, OpenSBLI is an explicit high-or…
The effect of flow confinement on laminar shockwave/boundary-layer interactions
David J. Lusher, Neil D. Sandham
Numerical work on shockwave/boundary-layer interactions (SBLIs) to date has largely focused on span-periodic quasi-2D configurations that neglect the influence lateral confinement…
Energy efficiency of finite difference algorithms on multicore CPUs, GPUs, and Intel Xeon Phi processors
Satya P. Jammy, Christian T. Jacobs, David J. Lusher +1
In addition to hardware wall-time restrictions commonly seen in high-performance computing systems, it is likely that future systems will also be constrained by energy budgets. In…
