| Popis: | In this paper, we show that the viscosity of a suspension can be drastically reduced if its particles are rotating faster than the surrounding liquid. We propose to induce particle rotation by applying a DC electric field to a suspension of insulating particles dispersed in a slightly conducting liquid (Quincke rotation). We have studied the flow of such a suspension in a rectangular channel and measure the increase of the flow rate induced by the application of an electric field along the velocity gradient direction (shortest dimension of the channel). |
