  • 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
