Nektar++: enhancing the capability and application of high-fidelity spectral/ element methods
David Moxey, Chris D. Cantwell, Yan Bao +14
Nektar++ is an open-source framework that provides a flexible, high-performance and scalable platform for the development of solvers for partial differential equations using the hi…
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…
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…
Analysis of the absorbing layers for the weakly-compressible lattice Boltzmann schemes
Hui Xu, Pierre Sagaut
It has been demonstrated that Lattice Boltzmann schemes (LBSs) are very efficient for Computational AeroAcoustics (CAA). In order to handle the issue of absorbing acoustic boundary…
Sensitivity analysis and determination of free relaxation parameters for the weakly-compressible MRT-LBM schemes
Hui Xu, Orestis Malaspinas, Pierre Sagaut
It is well-known that there exist several free relaxation parameters in the MRT-LBM. Although these parameters have been tuned via linear analysis, the sensitivity analysis of thes…
Optimal low-dispersion low-dissipation LBM schemes for computational aeroacoustics
Hui Xu, Pierre Sagaut
Lattice Boltmzmann Methods (LBM) have been proved to be very effective methods for computational aeroacoustics (CAA), which have been used to capture the dynamics of weak acoustic…
