Sb. Riffat et Kw. Cheong, TRACER-GAS TECHNIQUES FOR MEASURING AIR-FLOW IN DUCTS - A REVIEW, International journal of energy research, 19(6), 1995, pp. 461-477
A review of experimental work on tracer-gas techniques for measuring a
irflow and air leakage in ducts is presented. The paper also outlines
the requirements for further work in this area.
