The Irisk maps of the classroom when the thermal effect is considered with the air cleaner placed near the HUV at a higher elevation (1.3 m above the floor) compared with previous simulation cases (0.3 m above the floor) for an infector (a) in the front (case TA2H) and (b) in the middle (case TB2H) of the classroom. Note that the human figures in (a) and (b) are used for illustration purposes. The infector is modeled as a cuboid in the simulation.
