Fluid flows of engineering interest are mostly turbulent and viscous in nature. Therefore, designing engineering applications such as jet engines, cooling of electronics, industrial furnaces, etc., requires a thorough understanding of Real Viscous Flows. In this learning track, we will start with a dive deep into Laminar Boundary Layer Theory and understand the vital role it plays in how we model fluid behavior. We will then proceed through courses that incrementally add sophistication and build a foundation for learning the principles that govern these flows. We will discuss the Basics of Turbulent Flows. We will learn how engineers design piping and ducting systems that tackle Real Internal Flows. Moreover, we will also discuss how vehicles moving through fluids experience lift and drag forces in Real External Flows. Lastly, we will go Beyond Viscosity and get a taste of what lies ahead.
