Flow Through Trees

Flow Through Trees#

The flow’s velocity and turbulent kinetic energy are damped when the fluid pass through tree arrangements. Such situations are common on pedestrian comfort studies. A good benchmark case to test if the solver is capable of representing such tree structures can be found in Qi and Ishihara[1] and Kang et al.[2].

The measurements of flow profile are made for the average velocity and turbulent kinetic energy, which is defined as:

(1)#\[k=\frac{1}{2}\left(\bar{u'^{2}} +\bar{v'^{2}}+\bar{w'^{2}}\right)\]
