Study on Axial Flow Distribution Analysis for Flat-type Axial Flow Fan

薄型軸流ファンにおける軸方向流速分布解析に関する研究

The purpose of this research is to propose theoretical flow models between axial fan blades verified with flow visualization. The models based on lifting line theory will be useful to calculate the axial velocity of the fans. The flow visualization that will clarify vectors of the real flow around the blades consists of two steps as follows: first is flow image acquisition around rotating blades using an image rotating system the authors have developed, second is vectors acquisition from the images using PIV analysis. The authors conclude that the flow visualization can improve fan design.軸流ファンの翼間流れを理論的・実験的に把握しファンの設計に活用するため，揚力線理論に基づいて流れを予測する理論解析手法を構築し，また回転翼の実作動時における翼間流れを可視化・PIV計測することで，左記理論の妥当性を検証した．本理論を用いれば薄型ファンの設計に活用可能であることがわかったため報告する．
