CFD simulation of “pumping” flow mechanism of an urban building affected by an upstream building in high Reynolds flows
Energy and Buildings(2019)
Abstract
•Vortex shedding occurred around two identical buildings in tandem arrangement.•Upstream building influences the “pumping flows” of the downstream target building.•Vortex shedding frequencies at various obstacle spacings have been investigated.•“Pumping flow rate” is determined by both mean and fluctuating pressure differences.
