The present analysis of constant current anemometry in subsonic slip and transonic flows using the least square technique appeared to show that, based on Spangenberg's data, measured fluctuations would probably have substantial errors based on the large condition numbers calculated for the 6x6 ...

Hot Wire Measurements of the Suction Velocity and its Distribution on the ELFIN II-Wing Model with Hybrid Laminar Flow TechnologySuccessful experiments with the ELFIN II wing model were carried out in the transonic wind tunnel S1 of ONERA with a boundary layer suction system. However questions ...
Hot-wire anemometry techniques have been used for over 50 years to determine mean and unsteady characteristics of many types of complicated flow fields, The ability to interpret hot-wire data has been complicated by the techniques' sensitivity to different flow variables and the non-linearity ...

Then, the results obtained by hot-wire anemometry are presented in Section 3. In particular, we discuss the features of the wake characteristics, Reynolds stress components, and the degree of flow anisotropy according to airfoil shape error, Reynolds number and angle of attack. Moreover, for ...
The flow field is spatially sampled by traversing the probe in radial direction. If the whole duct cross section evaluation is desired, the probe is traversed additionally in circumferential direction. One of many complications of hot-wire anemometry is its sensitivity to external disturbances. Two ...
