Discrete vortex methods for the simulation of boundary layer separation effects on worker exposure / Michael R. Flynn and Cass T. Miller
Sumario: 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 experiments
