Influence of computational parameters on turbulence flow structure characteristic in two dimensional idealized urban street canyon for large eddy simulation / Norharyati Saleh

The use of Computational Fluid Dynamics (CFD) as a research tool has been utilized in many ways to predict the turbulent flow nature in an urban environment such as a street canyon. A review of past relevant studies on the atmospheric process in large or long street canyons indicates an arbitrary se...
