Our lives heavily depend on the two most important fluids on earth: Air and Water. They are everywhere: they make the atmosphere, most of the earth’s surface is covered with water, and most of our body is composed of water. Fluid Mechanics is the science of understanding how fluids, including air and water, behave. The challenge is that equations that govern dynamics of Fluids are very complex, impeding analytical solutions. Running experiments are also very expensive and difficult to conduct and measure. The advent of high performance computers, however, has given us a new tool to understand and analyze fluid mechanics problems. The objective of this mini-course is to introduce basics of Fluid Mechanics and Numerical Simulations to those who are interested to learn about this state-of-the-art technique. This is a project-based course and we will learn about conducting computational analysis via a commercial CFD software while working on a real-life problem. Computational Fluid Dynamics is becoming one of the most needed expertise in many industries including aerospace, ocean industries, chemical engineering, automobile industries, computers (particularly for cooling), and nearly all hardware industries.
