Title: Research on Estimation Method of Zero-lift Drag at Lower-Reynolds-Number
Abstract: According to the estimation formula of the laminar and turbulent frictional drag,establish the calculation model of the equivalent frictional drag coefficient to estimate zero-lift drag coefficient at lower Reynolds number.Through verifying and analysing the estimation method,research the trend that the zero-lift drag coefficient varies with Reynolds number at lower Reynolds number.The result shows that the estimation established method is reasonable,and this method accurately reflects the regular pattern that the zero-lift drag coefficient varies in larger Reynolds number range.
