Thermal Stratification Effects on Turbulence and Dispersion in Internal and External Boundary Layers

A synthetic-turbulence and temperature-fluctuation-generation method is developed and embedded in large-eddy simulations to investigate the effects of weak stable stratification (i.e. Richardson number R i ≤ 1 ) on turbulence and dispersion following a simulated rural-to-urban transition. The modell...
