Description/Abstract:
This report gives the results of experiments with small stacks discharging into gentle cross winds which showed that the cone of stack gas is bent toward the path of the wind and eventually travels along with the wind. The experimental work was divided into three parts which were the measurement at various levels above the stack and points downstream from stack of the dilution of ammonia tracer gas introduced into the air, measurement of air velocity at various levels above the stack and points downstream, and photographs of ammonium chloride smoke plumes issuing from stacks. Experimental work on the stacks discharging into cross winds was performed in both a large hallway with an aerovent fan at the exhaust end and a constructed wind tunnel with an adjustable roof. The eddy diffusion equation is useful in experiments for estimating the concentration of a contaminant at various points in a horizontal cloud. The Reynolds number is used to determine turbulence in the air produced by objects in the airstream. A drawing of the wind tunnel, tracings of the smoke plumes, graphic drawings of test results, a drawing of the eddy diffusion factor compared to the Reynolds number, a stack drawing, tables, and photographs are enclosed.
