Abstract
A method of turbulence mesurements at low velocities with V-shaped hot-wires is described along with associated probe arrangements. The present method is based on the simultaneous solution of exact nonlinear equations for the effective cooling velocities, thus providing instantaneous values of velocity components. The validity of the technique was tested for the measurement of turbulent velocity components which were artificially produced by shaking the hot-wire probe with an accurately known motion in a steady flow. Instantaneous velocities obtained with the proposed method were in almost perfect agreement with the corresponding imposed values.
