Abstract Studied in the present paper is the phenomenon of interaction of suspended particles with the fluid over a stretchable rotating disk. The physical insights into the resulting flow behavior and heat transfer rate of two phase equilibrium are the main targets. How the stretching contributes to the dusty flow character will be clarified. Governing equations of motion and energy are first transformed into similarity systems representing the fluid and dust stages. In the absence of dust particles, the whole system collapses onto the well-known von Karman rotating disk subject to a wall deformation in the radial direction. Numerical simulations are next performed to resolve the fluid and dust phases and their thermal responses to the interaction. The local wall shears, the wall slippage of the colloids, the far-field behaviors, and the heat transfer rates of both fluid and dust particles are eventually investigated graphically and tabularly in detail with physical insights.

悬浮在可拉伸旋转盘上的尘埃颗粒和两相传热

摘要 本文研究的是悬浮粒子与流体在可伸缩旋转盘上的相互作用现象。对两相平衡的最终流动行为和传热速率的物理洞察是主要目标。将阐明拉伸对尘土流动特性的影响。运动和能量的控制方程首先被转换成代表流体和灰尘阶段的相似系统。在没有尘埃颗粒的情况下，整个系统坍塌到众所周知的冯卡门旋转盘上，并受到径向壁变形的影响。接下来进行数值模拟以解决流体和灰尘相及其对相互作用的热响应。局部壁剪切、胶体壁滑移、远场行为、
