Graphene and 2D Materials in Heat Transfer: Fundamentals and Applications

為了解決Micro nano的問題，作者 這樣論述：

Heat transfer is a major engineering challenge that has implications in several areas including space, energy, transportation, manufacturing, and medicine. Graphene and other 2D materials have outstanding thermo-physical properties. As a result, these materials are being exploited in various appl

ications. Although several reports have been published on fundamental heat transfer aspects of such materials, the topic remains challenging to understand for many who are new to it. Graphene and 2D Materials in Heat Transfer: Fundamentals and Applications aims to provide readers with the most recen

t information on the synthesis and applications of graphene in heat transfer. Furthermore, mechanical and thermal properties of 2D materials, solid-liquid interface phonon transfer at the molecular level, methods and observations of transport phenomena in nano-micro domains will be addressed. The bo

ok also offers detailed coverage of the emerging applications of 2D nanofluids and nanolubricants as alternatives to conventional heat transfer fluids The book explores applications in microchannel heat sinks, micro heat exchangers, and micro heat pipes, molecular dynamics (MD) simulations for heat

transport problems related to 2D materials and applications. In addition, convective heat transfer approaches for 2D materials and nanocomposites are also addressed. This is an important reference source for materials scientists and engineers who want to learn more about how graphene and other class

es of 2D materials are being used as heat transfer agents.

鎢微探針的電化學製程特性分析與模擬

為了解決Micro nano的問題，作者林佳勳 這樣論述：

鎢本身硬度高、使用壽命長具有良好導電性與耐腐蝕等優點，在半導體產業是不可或缺的角色，由於鎢本身材質太硬又脆導致在傳統產業加工時不容易切削，不僅會傷及工件也會造成加工表面品質不良，用電化學加工的方式去進行鎢棒的製程反而會讓加工表面光潔度高、 品質穩定等優點，針對產業的需求鎢針屬於一種消耗品需要去大量生產，而半導體產業追求微小奈米化，讓許多探討探針相關的研究人員都朝向奈米探針製程去做改良，但是在模擬方面的探針研究相對來說少很多，本文應用COMSOL軟體建構鎢針製程的模型，並用COMSOL Multiphysics進行多重物理有限元素分析，針對鎢針製程的參數、幾何、電流分佈、電極反應軟體建立一套數

值模型方法模擬探針的製程，日後就不需要完全依賴實驗去生產探針，可以先藉由給定的參數去計算模擬來得知結果，對於模擬分析我們可以減少實驗的次數並節省下時間並對業者提供鎢針模擬製程之參考。

超疏水性在結露狀況下對氣冷式熱交換器性能的影響

為了解決Micro nano的問題，作者莫尼實 這樣論述：

濕空氣冷凝是熱管理系統中常見的過程，在冷凍空調循環中尤為重要，冷凝現象發生於當熱交換器，特別是蒸發器，在低於空氣露點的溫度下操作時。此現象將會導致鰭片側的冷凝液滴(膜)滯留(retention)與橋接(bridging),進而造成風機壓降與能耗的增加。本研究旨在開發一種超疏水熱交換器，通過其疏水特性，最大限度地減少冷凝水的滯留和橋接。本研究提出一種新型的超疏水性鰭片換熱器設計構想，採用傾斜鰭片排列以達到最小壓降和最大節能效果。本研究從熱傳與壓降性能的觀點切入，將新型超疏水性傾斜鰭片換熱器與其他換熱器作比較分析，分別為：超疏水水平鰭片換熱器、親水性傾斜鰭片換熱器、與親水性水平鰭片換熱器。此外，

本研究藉由改變不同的操作條件，如：進氣溫度、相對濕度和鰭片間距，對這四種換熱器進行性能測試。親水和超疏水換熱器中分別以膜狀冷凝和滴狀冷凝模式為主。由於其表面的高潤濕性，親水換熱器會有較大的液滴脫落直徑。相比之下，超疏水換熱器中發生的 Cassie-Baxter 液滴模式，促使了較小的液滴脫落直徑。本研究建立了一個力平衡模型來分析液滴脫落直徑，模型參數包括了表面張力、慣性力與重力對液滴的影響。本研究基於韋伯數(We)與邦德數(Bo)與液滴脫落直徑，引入了一個新的無因次參數( )，該無因次參數 可預測表面的凝結水脫落能力，在給定的鰭片間距下， 越小代表凝結水脫落能力越好。研究結果表明，滴狀冷凝的

超疏水換熱器在濕空氣下的冷凝熱傳性能相較膜狀冷凝的親水性換熱器並未有顯著的提升，此結果可歸因於非凝結性氣體效應。然而，在壓降方面，超疏水性換熱器與親水性換熱器相比，可帶來高達70%的壓降降低，大幅提升節能效果。壓降的降低歸因於聚結誘發的液滴跳躍現象，使得冷凝水連續脫落。
