Abstract
The effect of vibration on the flow resistance of a shear-thinning fluid was investigated with a newly-designed pressure-scanning capillary viscometer. The experimental apparatus was designed to measure flow resistance continuously over a range of flow rates at a time. Low frequency vibration was applied perpendicularly to the direction of the flow. The effect of the transversal vibration was investigated for both Newtonian fluids and non-Newtonian fluids. The experimental results showed that the vibration had no effect on the flow resistance of the Newtonian fluids. However, the vibration caused a significant reduction of the flow resistance for the shear-thinning fluid. The reduction of the flow resistance was strongly dependent on both vibration frequency and amplitude.
