Anisotropy and shear-layer edge dynamics of statistically unsteady,stratified turbulence
Wingstedt, Emma My Maria; Fossum, Hannibal Eie; Reif, Bjørn Anders Pettersson; Werne, Joseph (2015)Direct numerical simulation data of an evolving Kelvin-Helmholtz instability have been analyzed in order to characterize the dynamic and kinematic response of shear-generated turbulent flow to imposed stable stratification. ... -
Large-eddy simulation of dense gas dispersion over a simplified urban area
Wingstedt, Emma My Maria; Osnes, Andreas Nygård; Åkervik, Espen; Eriksson, Daniel; Reif, Bjørn Anders Pettersson (2017)Dispersion of neutral and dense gas over a simplified urban area, comprising four cubes, has been investigated by the means of large-eddy simulations (LES). The results have been compared to wind tunnel experiments and ... -
Large-eddy simulations of dense-gas dispersion within a high-Reynolds number turbulent boundary layer
Wingstedt, Emma My Maria; Vartdal, Magnus; Reif, Bjørn Anders Pettersson (2017)Large-eddy simulations of flows over a backward-facing step with release of four different gases with increasing densities have been performed. The results have been analysed with particular emphasis on the part of the ... -
A model for the viscous dissipation rate in stably stratified, sheared turbulence
Fossum, Hannibal Eie; Wingstedt, Emma My Maria; Reif, Bjørn Anders Pettersson (2013)A model for the turbulence dissipation rate in stably stratified shear turbulence is developed and validated. The functional dependence of the model is derived from first principles and it represents a conceptually new ... -
Post-blast explosive residue-a review of formation and dispersion theories and experimental research
Abdul-Karim, Nadia; Blackman, Christopher S.; Gill, Philip P.; Wingstedt, Emma My Maria; Reif, Bjørn Anders Pettersson (2014)The presence of undetonated explosive residues following high order detonations is not uncommon, however the mechanism of their formation, or survival, is unknown. The existence of these residues impacts on various scenarios, ...
