Dewetting Fingering Instability in Capillary Suspensions: Role of Particles and Liquid Bridges
Lingyue Liu, Mete Abbot, Philipp Brockmann +3
This study investigates the fingering instability that forms during stretching of capillary suspensions with and without added nanoparticles. The dewetting process is observed usin…
Drop impact on a heated pre-wetted wall: deposition-on-crater splash regime
Lukas Weimar, Bastian Stumpf, Jeanette Hussong +1
The impact of a liquid drop with high Reynolds and Weber numbers on a wet solid surface typically results in the emergence, rising, and expansion of a corona-like thin jet. This ph…
Thermal Finite-Element Model of an Electric Machine Cooled by a Spray
Christian Bergfried, Samaneh Abdi Qezeljeh, Ilia V. Roisman +3
The need for higher power density in electrical machines require better cooling strategies. Spray cooling is a very promising and relatively simple technology to apply, but involve…
Drop impact onto a substrate wetted by another liquid: Corona detachment from the wall film
Bastian Stumpf, Ilia V. Roisman, Alexander L. Yarin +1
Drop impact onto a thin liquid film of another liquid is observed and characterized using a high-speed video system. A new mode of splash - a complete, simultaneous corona detachme…
Dynamics of collision of a spherical ice crystal particle with a perfectly rigid substrate
Ilia V. Roisman
Impact of single particle onto a rigid substrate leads to its deformation and fragmentation. The flow associated with the particle spreading on a solid substrate after impact is ex…
Leidenfrost temperature in sprays: role of the substrate and liquid properties
Fabian M. Tenzer, Julian Hofmann, Ilia V. Roisman +1
In this study the Leidenfrost temperature during spray cooling of very hot substrates is experimentally measured. The spray parameters, i.e. the drop diameters and velocities and t…
