Study of Air Distribution in Large Single-Room Shelters

Abstract

The report describes experimental studies performed to determine the effect of OCD-developed, manually powered ventilation equipment for ventilating large, single-room shelters and to evaluate the maximum size facility that can be ventilated with this equipment. The equipment used consisted of a 30-inch fan and an air distributional device called a Kearny pump. The equipment was operated using various configurations of apertures for air inlet and exhaust. During each test, airflow rate measurements were taken at heights of three feet and six feet above floor level using hot wire anemometers at measurement points marked off on the floor of the test facility. These measurements were used to develop iso-speed contours for airflow rates of 20 fpm and 40 fpm over the floor of the test facility.
