• 要約等: <p>The purpose of this study is to reduce the dependence of wall shear stress measurements using the sublayer plate method on the flow angle. This is achieved by focusing on the leading-edge geometry of the sublayer plate. This is done in this study by focusing on the leading-edge geometry of the sublayer plate. A two-dimensional channel flow is used to investigate this issue. The bulk Reynolds number is between 10,000 and 22,000. The wall friction coefficient of this channel flow is verified using a previous study. A calibration curve that converts the pressure difference before and after the plate to wall shear stress is shown. It is confirmed that the same characteristics of the conventional sublayer plate method are maintained even when the leading-edge geometry is changed. The sensitivity of the measurement when the leading-edge geometry is changed is also investigated. The dependence of the wall shear stress values on the inflow angle is then shown. The dependence on the inflow angle depends on the leading-edge geometry and can be reduced by up to 20%.</p>
