| 内容記述 | Wind tunnel experiments are conducted to investigate the effects of the turbulence intensity of a oncoming flow on the gaseous diffusion around two buildings. In the experiments, the turbulence intensity of the oncoming flow is varied by setting a mesh grid on the upstream of the measured section in the wind tunnel. Air flow characteristics such as mean velocity, turbulence intensity and wake length are measured by a hot-wire anemometer, and concentration distributions around models are investigated by a hydrocarbon analyzer using ethylene gas as tracer gas. From the experiments, the following conclusions are confirmed. As the turbulence intensity of the oncoming now increases, the concentrations on the rooftop of the low-rise model increases, while the concentrations on the gound surface between the models and on the upwind face of the high-rise model decreases. The length of cavity wake is also proportional to the turbulence intensity, and it is approximately 4 H for√</U^2_0>/√<U_o>=15.3%. | |||||
