Directional Effects of Human and Door Motions on the Transport of Aerosols Across a Doorway

Abstract

Human movement across a doorway and associated door opening and closing motions is an important mechanism of containment failure in protective rooms. Detailed information regarding the 3D, time-dependent air flow field and aerosol concentration field induced by the motions is of pivotal importance for the development of effective intervention strategies. This study used boundary-conformal moving mesh techniques to simulate air and aerosol transport from a contaminated room into a pressure-equilibrium clean room. The simulations were conducted with different directions of manikin movement and door swinging in order to analyze their individual and combined effects on aerosol transport. The res..
