摘要: To facilitate the research of mobile robot based odor source localization (OSL) and evaluate different strategies for OSL, numerical simulation plume in indoor ventilated environments is addressed. On basis FLUENT software package, 3-D wind field an environment calculated using Reynolds average approach, where real velocity measured by a anemometer taken as inlet boundary condition simulation. In fixed height, 2-D obtained superimposing normal-distribution fluctuating speed on advection velocity, built combining Farrell's filament concentration model with simulated field. Through comparing information recorded multiple sensor nodes ones, creditability established demonstrated.
