Transmission of a Pressure Signal through a Confined Bubble Array
Edgar Ortega-Roano, Devaraj van der Meer
Pressure changes travel at an infinite sound speed in an incompressible ideal fluid, opposite to what happens in a bubbly liquid, where the presence of bubbles adds compressibility…
Short-Time Force Response during the Impact of a Droplet with Gas Bubbles
Edgar Ortega-Roano, Devaraj van der Meer
The presence of gas or vapour bubbles may strongly influence the forces that occur during the impact of a liquid mass onto a solid. Here, we study this effect numerically, in a wel…
Clogging of non-cohesive suspensions through constrictions using an efficient unresolved CFD-DEM solver
Edgar Ortega-Roano, Mathieu Souzy, Thomas Weinhart +2
When objects are forced to flow through constrictions their transport can be frustrated temporarily or permanently due to the formation of arches in the region of the bottleneck. W…
Autothermotaxis of volatile drops
Pallav Kant, Mathieu Souzy, Nayoung Kim +2
When a drop of a volatile liquid is deposited on a uniformly heated wettable, thermally conducting substrate, one expects to see it spread into a thin film and evaporate. Contrary…
Diffusive and convective dissolution of carbon dioxide in a vertical cylindrical cell
Daniël P. Faasen, Farzan Sepahi, Dominik Krug +4
The dissolution and subsequent mass transfer of carbon dioxide gas into liquid barriers plays a vital role in many environmental and industrial applications. In this work, we study…
