Aerosol particle wall loss rates were determined experimentally in a spherical continuous stirred tank reactor. Tbe particle size and mixing rate dependences are shown to agree with β=12k_eD/Rπvʃ^nv/2√k_2D_0 te^t/e^t-1dt+v/4R3 the theoretical result of Crump and Seinfeld, in which the particle loss coefficient β is related to particle diffusivity D, particle settling velocity r, the coefficient of the eddy diffusivity k_e, and vessel radius R. For the vessel used in these experiments, k_e was found to be proportional to the 3/2 power of the volumetric now rate, in accordance with theoretical expectations. Results of a similar nature may be expected to hold in vessels of arbitrary shape.
