Performance of drag force models for shock-accelerated flow in dense particle suspensions
Andreas Nygård Osnes, Magnus Vartdal
Models for prediction of drag forces within a particle cloud following shock-acceleration are evaluated with the aid of results from particle-resolved simulations in order to quant…
Particle-resolved simulations of shock-induced flow through particle clouds at different Reynolds numbers
Andreas Nygård Osnes, Magnus Vartdal, Marianne Gjestvold Omang +1
This study investigates the Reynolds-number dependence of shock-induced flow through particle layers at 10\% volume fraction, using ensemble-averaged results from particle-resolved…
Numerical investigation of shock wave particle cloud interaction in cylindrical geometries
Andreas Nygård Osnes, Magnus Vartdal, Marianne Gjestvold Omang +1
This study investigates the interaction of a shock wave with a fixed layer of particles in cylindrical geometries using particle-resolved large eddy simulations. The curvature radi…
Linear motion of multiple superposed viscous fluids
Magnus Vartdal, Andreas Nygård Osnes
In this paper the small-amplitude motion of multiple superposed viscous fluids is studied as a linearized initial-value problem. The analysis results in a closed set of equations f…
The role of wave kinematics in turbulent flow over waves
Espen Åkervik, Magnus Vartdal
The turbulent flow over monochromatic waves of moderate steepness is studied by means of wall resolved LES, and cover a range of wave ages and Reynolds numbers. We compute the Four…
Computational analysis of shock-induced flow through stationary particle clouds
Andreas Nygård Osnes, Magnus Vartdal, Marianne Gjestvold Omang +1
We investigate the shock-induced flow through random particle arrays using particle-resolved Large Eddy Simulations for different incident shock wave Mach numbers, particle volume…
