Researchers Map 3D Air Patterns Near Walls

Researchers at Japan's National Institute of Technology and The University of Tokyo successfully mapped hidden three-dimensional air patterns near a heated wall using a mirror-assisted imaging technique. Published in International Communications in Heat and Mass Transfer in 2026, the study utilized a 12-camera system and identified a transition range corresponding to local Grashof numbers of 1.44 × 10⁹, 2.16 × 10⁹.
