• 論文の詳細を見る

• In this paper, the author represents the drag coefficients that are necessary when we design an axial-flow compressor. These drag coefficients are based on the data of the single-stage axial-flow blower, which is applied to the measurement of total pressure distribution on the relative flow field in down-stream of the rotating blades by a special technique. From this study, the author proposes new formulas of the drag coefficients as follows : 1) Profile drag coefficient [numerical formula] (Conventional formula) 2) Secondary-flow drag coefficient [numerical formula] 3) Annulus drag coefficient [numerical formula] 4) Tip clearance drag coefficient [numerical formula]
