Abstract

A verification of the Clauser method was carried out by numerically solving the momentum integral equation and the result was compared with the value of the friction velocity determined from a least-squares fit of the experimental data with an analytical description of the universal law of the wall. Velocity measurements using a boundary-layer hot-wire probe were performed in a test section contained in a suction-type wind tunnel. The velocity profiles were measured using an IFA-100 (TSI) hot-wire anemometer and a boundary layer probe mounted on a precision three-axis measurement system. A lower limit of momentum-based Reynolds number (Reδ₂) for a logarithmic profile in the turbulent boundary layer was of the order of 350. The results revealed that the value of Reδ₂ at the first position was 770 and the freestream turbulence levels were in the range 0.30.4%.
