Fundamental numerical studies of thermal stratification effects in idealized urban areas: Weakly unstable thermal stratification effects on the elongated roll-structures downstream of a high-rise building, and its potential effect on pollutant dispersion in urban areas

Pollution in urban environments is increasingly becoming a major concern for our societies which, together with the increasingly powerful capabilities provided by computational fluid dynamics (CFD), has made pollution dispersion a common topic of research during the last two decades. Several factors are relevant to the dispersion of pollutants...
