Abstract

This study investigates the characteristics of human exhalation during breathing and coughing. Experiments employing one breathing thermal manikin are conducted in a full-scale test room with a mixing ventilation system. Two artificial lungs are used to generate discontinuous airflows with specific flow rates and temperatures for breathing and coughing, respectively. Smoke visualizations are conducted to show the formation, movement and vanishing of the exhalation jets from nose and mouth separately. The transient velocity distribution generated by breathing and coughing in different places are analyzed.
