Abstract
Measurements via Laser-Doppler-Anemometry (LDA) were performed with th e electrorheological fluid P 1723 (laboratory sample supplied by Rober t Bosch GmbH, Stuttgart) inside a flat channel with electrically condu cting walls. The results show i) marked quantitative differences to da ta obtained viscometrically and ii) large velocity fluctuations in the bulk regions of the channel. Formation of - possibly transient - stru ctures would be consistent with this result.
