The velocity profiles of a flow along an inclined agar with different water contents wall were measured by a PIV method. The velocity profiles on the agar were compared with the exact solution of the thin flow driven by the gravity along an inclined wall. The slip velocity was observed for the velocity profiles of flow on the agar. The wall shear stress decreases with in creasing the rate of water contents of the agar. The results show the friction drag of water flow reduces in the case of the hydro-gel wall., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064575006, レポート番号: JAXA-SP-09-014}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {ハイドロゲル壁面上の流れ}, volume = {JAXA-SP-09-014}, year = {2010} }
