🛖 Thatched Hut Hearth Smoke: Stack Ventilation and CO Exposure (2D)

Cross-section of a thatched beehive hut with a burning hearth, in which warm air rises out through the ridge and fresh air enters at the door. Set the hut size, the fire power, the carbon monoxide yield of the fire, the opening area, the outdoor temperature and the wind speed, and see the warm-air excess, the ventilation flow, the air changes per hour and the carbon monoxide level over an evening against the health guidelines. The well-mixed balance, the mass balance, the stack-effect solution and the time to a guideline are checked numerically, with four in-page numerical checks.
