Impact of boiling liquid droplets: Vapor entrapment suppression
Bernardo Palacios-Muñiz, Edgar Ortega-Roano, Yee Li +3
There hardly is a fluid mechanics phenomenon attracting more attention than the impact of a droplet, due to its undeniable beauty, many applications and the numerous challenges it…
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…
