This blog explains how to set up industrial simulations using the Incompressible Navier-Stokes (IncNS) Solver in Nektar++. The geometry here is the Imperial Front Wing (IFW), an unraced front-wing configuration of the McLaren MP4-17D race car. Combined with a rolling wheel, it is a representative model for modern open-wheel motorsports, especially Formula 1 front-wing designs.
HX1 (or Hex) is the new High Performance Computing Cluster provided by the Research Computing Services at Imperial College London. This post describes how to set up Nektar++ on HX1.
Taylor-Couette (TC) flow involves fluid motion between rotating concentric cylinders, one of the key problems in fluid dynamics. In this study, we aim to focus on the effects of ‘sinusoidal’ radial heating on the TC flow dynamics.
Underwater radiated noise from shipping activities and offshore wind turbine construction/operation acts as a stressor for marine mammals. Using Nektar’s high-order spectral element method the Acoustic Perturbation Equations were numerically solved to explore the complex physics of acoustic scattering and interference of acoustic waves.
The latest version of Nektar++, v5.5.0, was released on the 31st January 2024.

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.

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.
The 7th annual Nektar++ Workshop will bring together developers and users of all experiences to hear about new and future developments in the Nektar++ spectral/hp element framework and the exciting science and engineering being undertaken with the code.
