Monte Carlo simulation of discotic liquid crystals. The anchoring can be tuned at either substrate by varying the extent to which a particle is allowed to penetrate it. If the anchoring at the two substrates are very different, there is a linear variation from planar alignment at one substrate to homeotropic at the other. Video for the EPT 2022 Photo competition.

In this presented work, we have used Direct numerical simulation of a bubbly and buoyant turbulent flow and showed the break-up and coalescence of bubbles due to the maintained turbulence. Vertical component of fluid velocity with contours of vof=0.5 representing the bubbles are shown in the depicted picture. Photo for the EPT 2022 Photo competition. Photo: Shahab Mirzareza/NTNU

It’s a high-speed video with a framerate of 1000 fps, recorded with a Photron SA5 camera at the Waterpower Laboratory at NTNU. It shows the development of air bubbles in water within a 20 kHz ultrasonic field, and the representative filamentary bubble structures. Enjoy viewing science that seems somewhat unearthian.

Animation of isosurfaces of normalized, phase-averaged swirl strength. The isosurfaces are colored by the normalized vorticity about the x-axis. The animation shows all phases and can be looped. Fields are obtained experimentally using Shake-the-Box (4D Particle Tracking Velocimetry) and fine-scale grid reconstruction.Photo/Video for the EPT 2022 Photo competition.

Un-edited DSLR photograph of two actuator discs in the water channel. The discs are viewed head-on, the lens is focused on the downstream one. This allows us to see through the upstream one. Photo/Video for the EPT 2022 Photo competition. Photo/Video: Johannes Næsset Hillestad/NTNU

Plot of particle tracks in the wake of a model wind turbine. The tracks are colored by the normalized streamwise velocity.
