Computational Fluid Dynamics for urban physics: Importance, scales, possibilities, limitations and ten tips and tricks towards accurate and reliable simulations (2015, background): “Security refers to pollutant dispersion and warning systems for toxic accidents and terrorist attacks [34-46], detection and warning for destructive meteorological phenomena, avoidance of occurrence and impacts of windborne debris [61-64] and fire safety in terms of limiting both occurrence and spre”
On the Values for the Turbulent Schmidt Number in Environmental Flows (2017, background): “Tominaga and Stathopoulos [67] reviewed a number of previous studies related to the application of optimum values of Sct for engineering flow fields relevant to atmospheric dispersion, such as jet-in-cross flow, plume dispersion in boundary layer and dispersion around buildings.”
CFD Modeling of Pollution Dispersion in Building Array: Evaluation of turbulent scalar flux modeling in RANS model using LES results (2012, background): “…number, Sct, which is defined as the ratio of the eddy viscosity to the eddy scalar diffusivity, can provide better results in concentration diffusion in comparison with the case with usual values (0.7-0.9) (e.g. Di Sabatino et al., 2007; Tominaga and Stathopoulos, 2007; Blocken et al., 2008).”
CFD modelling of small particle dispersion: The influence of the turbulence kinetic energy in the atmospheric boundary layer (2009, background): “In several studies (e.g. Di Sabatino et al., 2007; Tominaga and Stathopoulos, 2007; Riddle et al., 2004) it is suggested that for the modelling of dispersion in urban areas the turbulent Schmidt number should be lower than the standard value of 0.”
The physical oceanography of the transport of floating marine debris (2020, background): “The value of this Schmidt number is an open question (Tominaga and Stathopoulos 2007, Gualtieri et al 2017).”
Numerical simulation of dispersion around an isolated cubic building: Model evaluation of RANS and LES (2010, result): “This is why the smaller value of turbulent Schmidt number worked well in the previous studies [4, 5, 21].”
