• 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. Light is the most beautiful way we see energy. This series of photos, taken during the aurora in Trondheim on March 23, 2024, focuses on this theme. I rushed to the NTNU campus and captured these photos in front of the EPT [Varmeteknisk] Building. Watching the aurora provides a rare opportunity to witness the beauty of Earth's celestial phenomena through the photons emitted when charged particles from the solar wind collide with the atmosphere - they are all about the energy. The first photo is named "Light Trails in Front of the Varmeteknisk Building"; The second photo is named "Energized Aurora's Touch on Classic NTNU"; The third photo is named "Vibrant Energy Flow of the Aurora: A View from EPT's Front Door".

Video of the morning fog on the fjord at Trondheim harbour from NTNU viewpoint: we witness the beautiful interplay of saturated condensation and evaporation, showcasing the dynamic principles of psychrometrics. As the fog forms and dissipates, it visually represents the changes in moisture content and temperature, fundamental to understanding air-water vapor interactions. Photo: Azimil Gani Alam/NTNU

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
