- Part 2: Study on Improvement of Analysis Precision of Flow Noise
Abstract
In order to improve the precision of predicting the fluid noise generated from an air conditioning duct, the analysis domain in fluid acoustic linkage analysis was studied and mesh size as an appropriate condition were studied using a blank duct without a specimen. As a result of studying consistency with the experimental results, it was found necessary to consider unevenness of the flow ground, and to divide the CFD mesh into at least 1/20 of the target wavelength. Furthermore, comparing the experimental results with a prismatic and partition plate model using the selected conditions, we studied the reproducibility of fluid acoustic linkage analysis.
