Numerical study of the effects of human body heat on particle transport and inhalation in indoor environment

► CFD technique presented to integrate gas-particle two-phase flows and heat transfer. ► Body heat causes a significant uprising airflow on the downstream side of the human body. ► The importance of body heat on particle inhalation is associated with the occupant orientation relative to the free stream. ► Body heat has a significant effect on particle inhalation when the occupant is back to the wind.
