各位同學：



由於週二2/20 登記排加簽的同學非常多，以下幾點說明，盼同學們理性評估後再決定是否加選本班。

(1) 週二2/20 公佈的加選規則，由於上課有錄影，因此不會再改變。但因為教室座位有上限，因此不會再受理登記排加簽。

(2) 我的加選規則是依循歷年來本人開授課程的加簽與停修經驗而定，建議同學們應該更勇於嘗試不同的授課語言以及教學方式。

(3) 這門課是一門必修課，會有必修課程的要求以及考核重點，也會有不通過Fail的狀況。這門課程後續領域專長的進階課程為黏性流體力學或連體力學，為協助有興趣同學們能順利銜接相關課程，因此會安排約九小時的線上補課，這些補課內容也將會是考核的重點項目。

(4) 基於種種因素，這門課不管修課人數多寡，只會有一位兼任助教協助批改作業與考試。若屆時因為人數眾多，導致作業批改、成績核算的延遲，也只能請同學們包容海涵。

(5) 週二2/20 登記加選的人數當中，應該有很多同學是下課後從別班來登記的。各位同學都是聰明睿智的成年人，相信各位同學都知道買鞋子要先試穿，買食物要先試吃，加簽一門課要先聽過的道理。若是因為盲目選擇，導致最終學期成績不如期望，請不要反過頭來怪老師或助教，因為這畢竟是你做的選擇。

(6) COOL 更新選課名單有它的作業時間，加選上之後，請務必收看 2/20 的錄影，來了解上課的方式，評分的規則，老師的要求，課堂的規矩等。如果最後發現這些要求是你無法配合，或是你不贊同的，請在線上加退選結束之前盡速退選，以免衍生後續爭端。

祝各位同學新春愉快、學業精進。

Fluid mechanics concerns the kinematics and dynamics of fluid flows as well as the governing force and deformation relationships for fluids at rest or in motion. The science or study of fluid mechanics thus has broad applications in both academia and industry such as atmospheric sciences, geophysics, ocean and coastal engineering, planetary sciences, biological engineering and physiology, agricultural sciences, building and architecture, material or polymer processing, micro and nanofluidics, groundwater flows, hydraulics, mud flows, body armor, sports sciences, as well as energy, aerospace, automobile, and naval industries.

As a 3-unit introductory core course directed towards mechanical engineering sophomores, we shall introduce, examine, and discuss the underlying physics and mechanisms governing the mechanical responses and behavior of Newtonian fluids and fluid flows, that is, fluids or flows exhibiting linear stress and strain rate relationships or of constant viscosity. We shall also lay down or establish the theoretical and mathematical foundations so as to derive the governing Navier-Stokes equations for describing or predicting the fluid velocity, pressure, stress, strain rate, lift, and drag during flow motion.

Topics covered in this class generally include:
fluid statics, Reynolds transport theorem, control volume analysis, inviscid flows and applying the steady/unsteady Bernoulli equations, viscous flows of Newtonian fluids and the Navier-Stokes equations, dimensional analysis and the Buckingham pi theorem, the boundary layer approximation and the momentum integral analysis, lubricating unidirectional and creeping low Reynolds number flows, distinction between laminar and turbulent flows, and Reynolds Averaged Navier-Stokes.

Hopefully, with the background knowledge and foundations established in this class, students can not only have a better understanding towards thermofluid sciences, but also be in a better position to take on advanced courses such as fluid mechanics (II), viscous fluid flows, advanced heat transfer, continuum mechanics, computational fluid dynamics, combustion, gas turbines, rheology, continuum electromechanics (EHD, MHD, FHD, ER, MR), compressible fluid dynamics, ideal fluid flows, convection heat transfer, etc. offered by the mechanical engineering department or at the University.
