The diffusion process of kitchen gas exhausted to the outdoor air surrounding a multi-unit housing facility

This  paper  examines  the  process  by  which  the kitchen exhaust from a dwelling unit diffuses throughout the other dwelling units in a seven-story housing facility. The diffusion process was examined by tracer gas measurements and compared to computer simulation. Results showed that kitchen gases exhausted from a central unit pollute all units on that entire floor and will vary in concentration depending on the wind direction.
