  1. Discrete vortex methods for the simulation of boundary layer separation effects on worker exposure.

    Article - En anglais

    The technique is employed here, with appropriate modifications, to simulate boundary layer separation around a worker and to assess the implications for exposure.

    Approximations include: (1) representation of the worker as a two dimensional elliptical cylinder; and (2) contaminant transport by vortex shedding exclusively.

    The model results in estimates of breathing zone concentration that are in reasonable agreement with laboratory wind tunnel experiments.
