An investigation of air inlet in simulating the dispersion of indoor contaminants via computational fluid dynamics

The aim of the study is to validate CFD approaches for the simulation of the dispersion of gases and vapors in an enclosed space at different flow rates, and to show the impact of one important determinant of simulation accuracy.CFD results and measurements were compared, showing a good correspondance for the pollutant concentration when the boundary condition was a profiled velocity inlet and not an uniform velocity inlet.
