Analysis of the Effect of Boundary Conditions in Airborne Contagion Risk in a Naturally Ventilated Classroom via Large Eddy Simulation
摘要
The effect of boundary conditions over the predicted risk of airborne infection by means of coupling Well’s hypothesis with high resolution Large Eddy Simulations is explored. Results are compared with the analytical Wells-Riley model and spatial risk inhomogeneities and flow patterns are discussed. This study contributes to two currently almost unexplored aspects of indoor contaminant distribution: the sensitivity to BC and the extent of the applicability of the perfect mix hypothesis. Results show them both to be significant.
