Novel design of rotating disk for improving separation efficiency of microfiltration by CFD
, 2014 碩士本研究使用計算流體力學(CFD)的方法來討論迴轉盤結構對速度和剪應力分佈的影響，其中結構的改變包含了迴轉盤葉片的種類與數目。研究選用的模組為內置迴轉盤的單一圓柱形濾室，並且將濾膜固定在靠近濾室底部的多孔性支撐材。本研究利用Fluent計算流體力學軟體來模擬三個維度之模組內部流場，其數值方法為網格有限體積法與紊流中的RNG k-epsilon模式進行連續及動量守恆方程式求解，並且選用不同迴轉盤結構與改變操作條件進行分析探討。迴轉盤的操作轉速設定至3000 rpm並且選用進料流速範圍從1.18 m ...

Load Distributing Metamaterials Via Discrete Optimization
Advanced Functional Materials, EarlyView.Mechanical metamaterials are computationally optimized to homogenize transmitted forces by minimizing the spread of reaction forces. The resulting architectures transform localized loading into broader, more uniform force distributions and experimentally demonstrate robust load spreading under quasi‐static and impact loading.
