Correction of Anisokinetic Sampling Errors.
Nelson, William G.
Gas flow patterns at a sampling nozzle are described in this presentation for the 12th Conference on Methods in Air Pollution and Industrial Hygiene Studies, University of Southern California, April, 1971. Three situations for sampling velocity are illustrated and analyzed, where the flow upstream of a sampling probe is: (1) equal to free stream velocity (isokinetic sampling), (2) greater than free stream velocity, and (3) less than free stream velocity. Vitols' method is examined in detail. (BL)
