The flow around a pirn rotating at high speed was analysed and considered by using parameters as numbers of revolutions and irn surface conditions.The results obtained from this analysis were as followed:1) The flow around the rotating pirn with the boundary conditions of numbers of revolutions and pirn surface conditions can be analysed.2) The velocity vector of flow in the proposed analysis has good agreement with experiment results for the previous described conditions.3) From the flow analysis by FEM (finite element method), we can learn contour of Stokes' stream function, vortexes and circumferential reverse flow which can't be easily obtained from experiment. 目的 巻糸体の回転数や表面状態をパラメーターとして, 高速回転する巻糸体周りの流れ場を有限要素法により解析して, この結果を先に発表している実験結果と比較, 検討しながら考察する.成果 本研究によって得られた結果を以下に示す.1) 巻糸体の回転数や表面状態の境界条件の扱いを含めて, 巻糸体周りの流れ場を解析することができた.2) 巻糸体周りの速度ベクトル解析値は, 前報の各条件下の実験結果と比較してほぼ一致した.3) 流れ場解析結果から, 測定実験では容易に得ることのできない流れ関数や渦度の等値線及び円周方向の流れの逆流等を知ることができた
