In this paper, a novel approach for tracking moving structures in multiphase flows over larger axial ranges is presented, which at the same time allows imaging the tracked structures and their environment. For this purpose, ultrafast electron beam X-

Capillary trapping plays a central role in the geological storage of CO2, oil recovery, and water soil infiltration. The key aim of this study is to investigate the impact of surface properties (wettability, roughness, heterogeneous mineral compositi

In this paper we present detailed Euler-Euler Large Eddy Simulations (LES) of dispersed bubbly flow in a rectangular bubble column. The motivation of this study is to investigate potential of this approach for the prediction of bubbly flows, in terms

This paper describes the modelling of bubbly flow in a bubble column considering non-drag forces, polydispersity and bubble induced turbulence using the Eulerian two-fluid approach. The set of used closure models describing the momentum exchange betw

Due to the introduction of alternative aviation fuels, new methods and models are necessary which have the capability to predict the performance of combustors dependent on the fuel composition. Towards this target, a multi-component vaporization mode

Many fluid flow processes in nature and technology are characterized by the presence and coexistence of two ore more phases. These two- or multiphase flows are furthermore characterized by a greater complexity of possible flow phenomena and phase int
