Hot Film Anemometry

Unsteady flow measurements were performed to investigate the internal flow field of a torque converter, especially unsteady rotor/rotor-interaction in the region between pump exit and turbine inlet. Instantaneous flow data were measured with hot-film probes and a computer based data acquisition system. The commonly used ensemble averaging method was adapted to this special case with two independently rotating impellers. Velocity profiles of the flow in the relative frame of reference of the pump impeller were evaluated and they were used to generate a computer animation. The paper gives an overview over the test facilities and the background of the present investigations. It follows a discussion of some essential aspects concerning the use of hot-film anemometry. The methods used to evaluate the data are described in detail and measuring results of the region between pump exit and turbine inlet are presented.

The free oscillatory flow of a viscous fluid in a U-shaped tube is considered. A theoretical analysis (in which an axial flow is assumed and the start-up of the column is taken into account) shows, depending on the value of the similarity parameter γ, various regimes of the flow. Measurements of the velocity distribution are made using hot-film velocity probes, operated with a constant-temperature anemometer, and visualizations of the flow are performed. Experimental results are in good agreement with theoretical ones when the flow is laminar, and show the possible existence of turbulent flows. Critical values, at which the flow is disturbed over a more or less extended range of the successive oscillations, are determined for the similarity parameters γ and h0/R.
