The similarity of flow pattern around a high-rise building model in natural wind was studied. The relation between the unsteady flow fields and the pressure fluctuation on the buildings wall surface was investigated by field measurements, model tests in natural wind, wind tunnel experiments and numerical simulations. Based on these results, the dependence of the flow pattern formations on the Reynolds number clarified. The method of the measurement and the evaluation of the static pressure of atmosphere was also discussed. Finally, a new conception for the wind pressure generation on bluff bodies in the unsteady wind flow was presented.

研究了自然风作用下高层建筑模型绕流流态的相似性。通过现场实测、自然风模型试验、风洞试验和数值模拟，研究了非定常流场与建筑物壁面压力脉动的关系。基于这些结果，流型形成的雷诺数的依赖性澄清。讨论了大气静压的测量和评价方法。最后，提出了非定常风场中海崖体表面风压产生的新概念。
