ABSTRACT:
A method for predicting local concentrations of short-lived microparticles having an unstable composition in a room simply and in a short time is provided. The method for predicting the concentration distribution of microparticles includes the steps of determining a flow field in a room, determining the age-of-air distribution in the room on the basis of the flow field in the room, and converting the age of air into the concentration of the microparticles.
