The development of particle-depleted regions in dense suspensions of neutrally buoyant particles. We aim to measure the spatial variation of fluid speed and particle speed, and of particle concentration, across and along a pipe into which has been introduced a mixture of said particles and fluid. This problem has significance in mechanical and chemical engineering wherever particle/fluid mixtures are flowing. The expected outcomes are recognition of a major contribution to world research, as well as technological applications; one that motivates us is the blood shear in the bearings of a revolutionary Australian blood pump for cardiac assist that avoids both pivots and magnetic suspension for the single moving part.

中性浮力颗粒的致密悬浮液中颗粒耗尽区的发展。我们的目标是测量流体速度和颗粒速度的空间变化，以及颗粒浓度在管道中的空间变化，管道中已经引入了上述颗粒和流体的混合物。这一问题在机械和化学工程中具有重要意义，无论颗粒/流体混合物在哪里流动。预期的结果是承认对世界研究和技术应用的重大贡献；激励我们的是革命性的澳大利亚心脏辅助血泵轴承中的血液剪切，该血泵避免了单一运动部件的枢轴和磁悬浮。
