MAP20071017862Flynn, Michael R.Discrete vortex methods for the simulation of boundary layer separation effects on worker exposure / Michael R. Flynn and Cass T. MillerSumario: The discrete vortex method is a numerical technique for the solution of the two-dimensional Navier-Stokes equations in vorticity-transport form. The technique is employed here with appropriate modifications, to simulate boundary layer separation around a worker and to asses the implications for exposure. Approximations include: (1) representation of the worker as a two-dimensional eliptical cylinder; and (2) contaminant transport by vortex shedding exclusively. The model results in estimates of breathinsg zone concentration that are in reasonable agreement with laboratory wind tunnel experimentsEn: The Annals of occupational hygiene. - Oxford [etc.]. - nº 1, February 1991 ; p. 35-501.
