Course Description
Why do golf balls have dimples? How do insects walk on water? Why don't redwood trees grow taller than 400 ft? How do garden sprinklers rotate without external power? Would swimming in Venus's ancient carbon dioxide seas be harder than in Earth's water? These are just some of the questions we hope to explore in this 3-unit introductory fluid mechanics course for mechanical engineering juniors.
We'll cover fundamental concepts like the continuum assumption, velocity fields, and vorticity. Using mass conservation and Newton's laws, we'll analyze fluid motion and solve basic engineering problems. Starting with inviscid flows, we'll introduce viscosity for internal (pipe) and external (airfoil, bluff body) flows, as well as free-surface flows. Dimensional analysis will also be presented, which is very useful to understand the role of different parameters for complicated problems.
Course Objective
Learning Aims: Our goals and skills you will be expected to demonstrate by the end of this course.
To develop your understanding of the basic principles of fluid mechanics: you will demonstrate an ability to recognize the type of fluid flow that is occurring in a particular physical system. You will have an ability to choose the appropriate fluid mechanical principles needed to analyze fluid-flow situations.
To develop your skills in analyzing fluid flows through the proper use of modeling and the application of basic fluid-flow principles: You will demonstrate an ability to apply appropriate simplifying assumptions and basic fluid-flow principles to formulate a mathematical description of a simple fluid-flow system. You will have an ability to solve and analyze the mathematical equations for a simple fluid flow system.
To study specific knowledge regarding fluid-flow phenomena observed in mechanical engineering systems, such as flow in a pipe, boundary-layer flows, drag, etc: You will be able to recognize basic flow phenomena that are present in a typical engineering system. You will have knowledge of important practical results in common fluid flows and their physical implications.
To demonstrate your capacity to design an engineering related to fluid mechanics. You will have the ability to solve engineering problems related to fluid mechanics.
