Simulation of air infiltration through revolving doors

Air  infiltration  through  revolving doors may have significant impact on the heating load of commercial and institutional spaces, and may create discomfort to people. This paper modifies a 40-year old model by Schutrum et al. (1961), composed of two components: (1) estimation of air exchange between one segment of the revolving door and the indoor/outdoor and  (2) estimation   of  net  air infiltration rate.
