建築付帯物から発生する空力騒音の数値予測に関する基礎的研究  [in Japanese] BASIC STUDY ON NUMERICAL PREDICTION OF AEROACOUSTIC NOISE RADIATED FROM BALUSTERS OF BUILDINGS  [in Japanese]

Quantitative methods for predicting aeroacoustic noise radiated from balusters of buildings have been expected as a tool for its effective reduction. We applied a numerical method of solution based on Lighthill-Curle equation. As a basic step, we attempted to predict characteristics of the sound radiated by airflow around a row of square cylinders at Reynolds number 1000 by 2-dimensional analysis. We also made a comparison of solutions of an isolated cylinder wake flow at the same Reynolds number by 2- and 3-dimensional analyses, as a preparation for further improvement of the method.
