BASIC STUDY ON NUMERICAL PREDICTION OF AEROACOUSTIC NOISE RADIATED FROM BALUSTERS OF BUILDINGS

摘要

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 as Reynolds number 1000 by 2-dimensional analysis.
