Entry for EPT 2024 Photo Competition. Title: Blowing out a candle - Visualising heat waves with Schlieren photography Time series (left to right) showing blow out of a candle flame. Due to the difference in the refractive index of heated gas, the heat waves can be visualised by Schlieren photography. Light from a point source is aimed towards a spherical mirror which focuses the light back to a point, where a knife edge is placed to cut out undistorted light. In this way, any changes in the density caused by the candle, placed between the light and the mirror, appear as a sharp contrast (red/black) in the image due to refraction. Photo: Eirik Æsøy/NTNU

Entry for EPT 2024 Photo Competition. The FlameSheetTM combustor has the capability to operate with high hydrogen fuel blends due to a novel aerodynamically trapped vortex flame stabilization strategy and the corresponding increased flashback resistance due to its unique “U-bend” flow pattern, offering a carbon-free solution for the transition to pure hydrogen fueling. An optically-accessible laboratory-scale FlamesheetTM combustor has been developed to study the system dynamics during hydrogen operation. Photo: Qian Wang/NTNU

Entry for EPT 2024 Photo Competition. In this video, the transient structures arising from the dynamic operation of the sliding door are simulated. The transmission of passive scalar concentration between the isolation room (blue color) and the anteroom (red color), connected via a sliding door in the middle of a partition wall, is visualized from a top view on a plane situated 1 meter above the floor. The motion of the door initiates complex airflow patterns that can result in the escape of potentially contaminated air. Photo: Elyas Larkermani/NTNU

Larger droplets are distributed in the group close each other, as they grow at the expense of smaller droplets during condensation process.

Entry for EPT 2024 Photo Competition. In the course "TEP4220 - Environmental impact indicators for decision support" we had an interactive lecture where we collected scientific data by taking photos of species on campus with the app, "iNaturalist". The specie in the photo is an edible mushroom called "Matblekksopp" in Norwegian, "Lawyer's Wig" in English, and "Coprinus comatus" in Latin. Photo: Solveig Birgitte Jacobsen Aarak (student)
