Viscous spectral energy coupling across scales in generalised Newtonian fluids
Arthur Couteau, Panayotis Dimopoulos Eggenschwiler, Patrick Jenny
We investigate the spectral energy dynamics of turbulent flows with variable viscosity using direct numerical simulation of homogeneous isotropic turbulence of generalised Newtonia…
Non-Linear Super-Stencils for Turbulence Model Corrections
Jonas Luther, Patrick Jenny
Accurate simulation of turbulent flows remains a challenge due to the high computational cost of direct numerical simulations (DNS) and the limitations of traditional turbulence mo…
Sparse data assimilation for under-resolved large-eddy simulations
Justin Plogmann, Oliver Brenner, Patrick Jenny
The need for accurate and fast scale-resolving simulations of fluid flows, where turbulent dispersion is a crucial physical feature, is evident. Large-eddy simulations (LES) are co…
Spectral adjoint-based assimilation of sparse data in unsteady simulations of turbulent flows
Justin Plogmann, Oliver Brenner, Patrick Jenny
The URANS equations provide a computationally efficient tool to simulate unsteady turbulent flows for a wide range of applications. To account for the errors introduced by the turb…
Variational assimilation of sparse time-averaged data for efficient adjoint-based optimization of unsteady RANS simulations
Justin Plogmann, Oliver Brenner, Patrick Jenny
Data assimilation (DA) plays a crucial role in extracting valuable information from flow measurements in fluid dynamics problems. Often only time-averaged data is available, which…
A variational data assimilation approach for sparse velocity reference data in coarse RANS simulations through a corrective forcing term
Oliver Brenner, Justin Plogmann, Pasha Piroozmand +1
The Reynolds-averaged Navier-Stokes (RANS) equations provide a computationally efficient method for solving fluid flow problems in engineering applications. However, the use of clo…
