| 内容記述 | This report describes the results of wind tunnel experiments and numerical simulations about the flow and concentration fields around twin high-rise buildings. These experiments and simulations were conducted at Environmental Protection Agency during Dr. Ohba's tenure from April in 1992 through March in 1993 as a visiting scientist. From the wind tunnel experiments, it was found that, provided the twin high-rise building models were located such that the separation distance between the twin building models were longer than a building height, then upwind building would reduce the effects on the flow fields near the top of the downwind building model, and the separation distance would not substantially affect the magnitude of the downwind surface concentration contours for the downwind building. The numerical simulations based on a k-ε model were conducted about three basic types of high-rise buildings using a CRAY supercomputer in EPA. Comparing the simulated results with experimental data for twin high-rise building models, the velocities along the upwind face of the downwind high-rise building model were predicted a little stronger than those in experimental data. Therefore, the reverse flow was not as clearly defined as that in the wind tunnel experiments. The overal good agreement with the wind tunnel data was achieved. However, for a single high-rise building model, the concentrations on the downwind surface were predicted higher than those for the twin high-rise buildings because the wake length was predicted longer than those for the twin building models. It is thought that our k-ε model needs to improve the accuracy of prediction. | |||||
