Hoffert, M.I., W.G. Hoydysh, S. Hameed, and S.A. Lebedeff, 1975: Laboratory simulation of photochemically reacting atmospheric boundary layers: A feasibility study. Atmos. Environ., 9, 33-48, doi:10.1016/0004-6981(75)90052-9.

Using a smog-chamber-validated computer model for the photochemical kinetics of C3H6/NOx systems, it is shown that by proper choice of reactant concentrations and light intensities, the reaction rates can be sufficiently accelerated to yield ozone formation times of 30 s or less. These conditions permit study of photochemical smog formation in wind-tunnel-simulated atmospheric boundary layers with turbulent-mean flow velocities of 1/3 m/s over test sections 10 m long. Advantages and limitations of this technique for studying inhomogeneous mixing in reacting flows, the influence of complex topography and temperature inversions, and validation studies of urban air pollution dispersion models, are discussed in some detail. The method is particularly attractive for fundamental studies of nonlinear interactions in chemically reacting turbulent shear flows under controlled conditions unobtainable in real atmospheres. A specific experiment is proposed wherein C3H6/NOx mixtures are injected into a wind tunnel boundary layer in a test section irradiated by NO2-photolyzing ultraviolet lamps which drive the smog-forming reactions.
