Advances in implementation of the Incompressible Navier-Stokes-Fourier solver with variable material properties

Jan Pech (Czech Academy of Sciences) Extension of the Incompressible Navier-Stokes Solver is developed for the system coupled with the energy equation. Temperature field is considered as an active quantity, which influences the flow field since the material parameters (dyn. viscosity, density, thermal conductivity) are temperature dependent. A priori, we do not simplify the problem […]

Quasi-static magneto-hydrodynamic convection in a rotating cylinder

Anthony Rouquier (Coventry University) We present a numerical study of the onset of rotating magnetoconvection in a cylinder under the quasi-static magneto-hydrodynamic approximation using the spectral-element solver Nektar++. The aim of this work is to obtain a better understanding of the convection process in planetary cores, especially in the tangent cylinder region. To this end […]

A spectral/hp element method for magnetohydrodynamics

Alexander Proskurin (Altai state technical university) A magnetohydrodynamic solver, based on the Nektar++ spectral/hp element framework, is presented. The velocity and electric potential quasi-static MHD model is used. The Hunt’s flow in square cross-section duct, and its stability are explored as example. Exponential convergence is achieved and the resulting numerical values were found to have […]
