Influence of Urban Road Green Belts on Pedestrian-Level Wind in Height-Asymmetric Street Canyons
Atmosphere, 2022 This study was conducted to examine the effect on airflow of the shape of an urban road green belt in an asymmetrical street canyon. In this paper, the airflow field at pedestrian height in an asymmetrical street with different building height ratios ...

Theory and computations for breakup of unsteady subsonic or supersonic separating flows [PDF]
, 1994 This study of flow just beyond a breakaway-separation point presents a description of planar nonlinear unsteady effects over a fairly wide parameter range, for a subsonic or supersonic boundary layer at large Reynolds numbers.

Axial Flow in a Vortex in Karman Vortex Street.
Journal of the Japan Society for Aeronautical and Space Sciences, 1996 The vortex filaments in a Karman vortex street are usually not parallel to the axis of a circular cylinder perpendicular to a uniform flow in a low speed wind tunnel, but incline to the axis of the cylinder. The axial flow to the upstream direction in a vortex was observed by means of flow visualization in each vortex of the Karman vortex street.

Dynamics of vortex shedding from slender cones [PDF]
, 2009 PhDThe dynamics of vortex shedding from bluff bodies has been investigated experimentally for many decades, with the simple geometric case for the investigation being a uniform circular cylinder aligned with its axis normal to the flow. Even though
