Simulation of turbulent wings at various Reynolds numbers

Simulation of turbulent wings at various Reynolds numbers

Continuing with our efforts on understanding the effect of pressure gradient and curvature on turbulent wings, we have now constructed a database consisting of time and spatially resolved turbulence around wings at 4 Reynolds numbers, starting at the low Re=100k up to...
Non-conformal simulations in the high-order code Nek5000

Non-conformal simulations in the high-order code Nek5000

Our continuing work on extending the open-source code Nek5000, based on the high-order spectral element method, has now reached a level of maturity such that we can – for the first time – perform simulations of turbulence in complex geometries. Adaptive mesh...
Topology optimization for natural convection flows

Topology optimization for natural convection flows

Together with colleagues from Umeå University, we implemented in Nek5000 the possibility to perform high-order accurate topology optimization, useful for flows driven by natural convection. To obtain a design with a given length scale, we apply regularization...
