Open-source Framework for Transonic Boundary Layer Natural Transition Analysis over Complex Geometries in Nektar++
Ganlin Lyu, Chao Chen, Xi Du +2
We introduce an open-source and unified framework for transition analysis for laminar boundary layer natural transition at transonic conditions and over complex geometries, where s…
Stable, entropy-pressure compatible subsonic Riemann boundary condition for embedded DG compressible flow simulations
Ganlin Lyu, Chao Chen, Xi Du +1
One approach to reduce the cost to simulate transitional compressible boundary layer flow is to adopt a near body reduced domain with boundary conditions enforced to be compatible…
Nektar++: Design and implementation of an implicit, spectral/ element, compressible flow solver using a Jacobian-free Newton Krylov approach
Zhen-Guo Yan, Yu Pan, Giacomo Castiglioni +4
At high Reynolds numbers, the use of explicit in time compressible flow simulations with spectral/ element discretization can become significantly limited by time step. To alle…
Computational study on an Ahmed Body equipped with simplified underbody diffuser
Filipe F. Buscariolo, Gustavo R. S. Assi, Spencer J. Sherwin
The Ahmed body is one of the most studied 3D bluff bodies used for automotive research and was first proposed by Ahmed in 1984. The variation of the slant angle of the rear upper s…
Spectral/hp element simulation of flow past a Formula One front wing: validation against experiments
Filipe F. Buscariolo, Julien Hoessler, David Moxey +6
Emerging commercial and academic tools are regularly being applied to the design of road and race cars, but there currently are no well-established benchmark cases to study the aer…
Spectral/hp element methods: recent developments, applications, and perspectives
Hui Xu, Chris D. Cantwell, Carlos Monteserin +3
The spectral/hp element method combines the geometric flexibility of the classical h-type finite element technique with the desirable numerical properties of spectral methods, empl…
Implicit Large Eddy Simulation of a wingtip vortex at
Jean-Eloi W. Lombard, David Moxey, Julien F. A. Hoessler +3
In this article we present recent developments in numerical methods for performing a Large Eddy Simulation (LES) of the formation and evolution of a wingtip vortex. The development…
Influence of localised smooth steps on the instability of a boundary layer
Hui Xu, Jean-Eloi W. Lombard, Spencer J. Sherwin
We consider a smooth forward facing step defined by the Gauss error function of height 4-30\% and four times the width of the local boundary layer thickness . The boundary…
An adaptive selective frequency damping method
Bastien E. Jordi, Colin J. Cotter, Spencer J. Sherwin
The selective frequency damping (SFD) method is an alternative to classical Newton's method to obtain unstable steady-state solutions of dynamical systems. However this method has…
Encapsulated formulation of the Selective Frequency Damping method
Bastien E. Jordi, C. J. Cotter, Spencer J. Sherwin
We present an alternative "encapsulated" formulation of the Selective Frequency Damping method for finding unstable equilibria of dynamical systems, which is particularly useful wh…
