STRACHAN, P.J.  and  VON BACKSTROM, T.W.. Velocity measurement in a hydrodynamic torque converter. R&D j. (Matieland, Online) [online]. 2000, vol.16, pp.62-70. ISSN 2309-8988.

An experimental torque converter in which flow characteristics could be both observed and measured was manufactured and tested. Flow visualisation was carried out by means of fluorescent tufts, air bubbles and polystyrene particles, and from these visualisations, flow velocities and angles were determined by using video and still photography. Differential pressure probes were used for direct measurement of flow velocity at different stations in the flow path. Agreement between results obtained by these different methods was good. The torque converter performance was also simulated by means of a o ne-dimensional hydro-dynamic model, and acceptable overall agreement was obtained between measured parameters and the model's results.
