We prepared 4 kinds of textile fabrics that materials are different for this study and measured their yean density, the linear density of yarn by a unit of the tex, the thickness of them and Young's modulus. These fabrics are formed in the shape of the pipe with the adhesive and it is used to wrap a cylinder. A cylinder wrapped by the fabric is installed in a two-dimensional wind tunnel in order to perfonn mainly two aerodynamic experiments. When there is a bluff body in a flow, Karman vortex occurs in the wake. Two experiments are performed to investigate the change of the Karman vortex. The first experiment set up a Pitot tube in the wake side of the cylinder and measured the velocity distribution of the wake with a digital manometer connected to it. The second experiment measured the frequency of Karman vortex in the wake with a hot-wire airflow meter and FFT (Fast Fourier Transform) analyzer. From the provided results and the properties of the fabrics, we consider the influence that the cylinder wrapped in the fabric gives the flow.}, pages = {213--220}, title = {着衣状態にある物体まわりの流れに関する研究}, volume = {38}, year = {2009}, yomi = {ミシマ, タイシ and キクチ, マサノリ and ヒラノ, キミタカ} }
