Title Experimental studies on factory ventilation with large heat sources: Part 2 - Natural ventilation
Bibliographic information Oct. 1982, No.20, p.1-9. Illus. 8 ref.
Abstract Scale model studies were carried out on the natural ventilation of a factory building with a large heat source through air inlet openings in the working floors, in an attempt to develop a method which would take full advantage of the more marked vertical than horizontal temperature gradient. In the case of natural ventilation resulting from the density difference between columns of outdoor and indoor air, the values of the Archimedes' number in the model and under natural conditions were the same. A stratification method using the temperature gradient effect required a smaller area for vents than the conventional method and resulted in more economic ventilation designs.
