帶有植物的河道水流淺水紊流運動大渦模擬
The computational results of models are in satisfactorily agreement with the experimental data. all the results show the validity of the proposed models. the present k - l les and 3d k - l les model are proven to be new useful tools for the study on turbulent flow in open channel with a vegetated region

K - lles模型和3dk - lles模型為進行帶有植物的河道水流紊流運動數值計算研究，特別是對分析存在植物的河道水流運動形態及由於植物的阻礙在河道中產生的大尺度渦的形成、發展研究提供了一個新的研究途徑。
3. the characteristics of boundary layer ' s transition, shape and separation are researched. the details as follows : ( l ) airfoil surface is turbulent boundary layer flows ; ( 2 ) velocity figure changed unsteady near the point of boundary layer separation due to randomicity of turbulent flow ; ( 3 ) the airfoil have better state of boundary layer separation and poor stall characteristics because of the upper surface of airfoil is flat

給出了該翼型的附面層特性：翼型表面基本為湍流附面層；在靠近附面層分離位置處，速度型形狀、特別是靠近翼型表面的底部速度型形狀變化不定，是湍流流動的隨機性所致；該翼型具有較好的附面層分離形態，但在失速迎角附近，附面層分離形態變化劇烈、失速特性差，是翼型上翼面形狀較為平坦所致。
