Centro de Documentacion de Fundación MAPFRE - Discrete vortex methods for the simulation of boundary layer separation effects on worker exposure

Notes: 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 experimentsRelated records: En: The Annals of occupational hygiene. - Oxford [etc.]. - nº 1, February 1991 ; p. 35-50Materia / lugar / evento: Higiene industrial Contaminantes químicos Contaminación atmosférica Gases contaminantes Velocidad Aire Ventilación Ecuaciones matemáticas Métodos de análisis Ensayos Otros autores: Miller, Cass T.
