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.
Claims22
A method for predicting the concentration distribution of microparticles, comprising the steps of:
- determining a flow field in a room;
- determining an age-of-air distribution with a location of microparticles immediately after their generation delivered to the room or the location at which the microparticles are discharged into the room as a starting point, on the basis of the flow field in the room;
- and
- using conversion unit for converting the age of air with said location as the starting point into a concentration of microparticles;
- wherein said converting step converts said age of air into said concentration of microparticles using a predetermined relation defining a relationship between an elapsed time t and a concentration X of microparticles, based on a type of said microparticles and a generated amount of microparticles.
