A Study on the Noise Capability of Center Air Vents System

The conventional design methods of duct structure are summarized, and the structure designing of how to reduce its working noise and of layout drawing is simply described. The main task of this study is to generally discuss the connections’ structure between ducts and outlets via the CFD analysis, geometric structure analysis, and the comparison of how to find suitable locations to fix them. This essay will finally introduce a solution of how to optimize a structure of ducts and outlets, based on their results of the CFD analysis, the geometric data analysis, and the noise test.
