- Radially heated Taylor-Couette flow in Nektar++
Abhishek Kumar and Junho ParkFluid and Complex systems, Coventry University, Coventry Taylor-Couette (TC) flow involves fluid motion between rotating concentric cylinders, one of the key problems in fluid dynamics. Its behaviour varies from axisymmetric Taylor vortices to turbulence through different patterns. … Read more - Computational modelling of underwater acoustic propagation with Nektar++
Dr Wrik Malik, James Watt School of Engineering, University of Glasgow Underwater radiated noise from shipping activities and offshore wind turbine construction/operation acts as a stressor for marine mammals. Thus, there is an urgent need to develop accurate underwater noise … Read more - Nektar++ 5.5.0 ReleasedThe latest version of Nektar++, v5.5.0, was released on the 31st January 2024.

- NekMesh: An open-source high-order mesh generation framework
DOI: 10.2139/ssrn.4632754
We present NekMesh: an open-source mesh generation package which is designed to enable the generation of valid, high-quality curvilinear meshes of complex, three-dimensional geometries for performing high-order simulations. - Three-dimensional transition and forcecharacteristics of low-Reynolds-number flowspast a plunging airfoil
DOI: 10.1017/jfm.2023.735
The three-dimensional (3-D) transition of the leading-edge vortex (LEV) and the force characteristics of the plunging airfoil are investigated in the chord-based Strouhal number Stc range of 0.10 to 1.0 by means of experimental measurements, numerical simulations and linear stability analysis in order to understand the spanwise instabilities and the effects on the force. - Aeroacoustic Analysis of a Closely Installed Chevron Nozzle Jet using the High-Order Discontinuous Galerkin Method
DOI: 10.2514/6.2023-3831
Large Eddy Simulations (LES) in combination with the Ffowcs Williams - Hawkings method to study the influence of chevrons on the flow field as well as the noise produced by a closely installed M = 0.6 jet.
