, 2016 应用最小势能原理研究了薄膜在基底上撕脱的整个过程,重点考虑了薄膜弯曲刚度、撕脱角及界面黏附能对撕脱行为的影响,得到了薄膜在不同弯曲刚度和撕脱角下撕脱力-位移关系曲线以及撕脱过程中薄膜构型变化。结果表明,当撕脱角和黏附能一定时,薄膜弯曲刚度对起始撕脱过程(达到稳态撕脱前)有重要影响,撕脱力随弯曲刚度的增大而增大;而当薄膜达到稳态撕脱后,撕脱力保持不变。最大撕脱力受弯曲刚度、撕脱角及黏附能的影响,并非总是出现在稳态阶段,有可能在达到稳态之前撕脱力达到最大值。进一步分析了薄膜在粗糙基底上准静态撕脱过程 ...

基于近壁RANS模型的光滑壁突变为粗糙壁条件下平板湍流流动预测
针对湍流边界层在光滑壁面突变为粗糙壁面条件下的典型流动问题,本文开展了数值模拟研究。研究对象为充分发展的平板湍流边界层,其光滑段基于动量厚度的雷诺数为Re_theta=5950。研究重点在于评估雷诺平均纳维斯托克斯（RANS）模型在预测由粗糙度突变引发的内部边界层（IBL）演化过程中的适用性。计算采用双层k-epsilon湍流模型,并通过引入水动力粗糙度长度y0,模拟粗糙壁面对平均流场与湍流结构的影响。结果显示,在粗糙段起始处下游形成明显的速度发展区,其中速度剖面表现出下层受粗糙度控制 ...

, 2014 本文主要研究探討微米級金屬表面粗糙度之平面偏振散射光量測，以取代傳統的接觸式量測。在實驗方面，我們自行設計並且架設一套二維非接觸式的自動光學系統來量測微米級金屬表面粗糙度的散射光場，並自行撰寫程式加以分析。在試片方面，本文選用Ra = 0.05 μm、0.1 μm、0.2 μm、0.4 μm、0.8 μm、1.6 μm等，各種不同表面粗糙度的標準試片，針對散射角以每5度進行量測。本文研究結果證實此非接觸式系統可精準量測出微米級金屬表面粗糙度與表面特徵。南台科技大學補正完畢國內20140821 ...
