In this course, we will learn about the basics of viscous laminar flows. These flows can be bounded (internal) or unbounded (external). First, we will identify some important dimensional numbers and use them to non-dimensionalize the Navier-Stokes equations. Next, we will learn about the various fluid forces acting on an object in unbounded flows and categorize them as lift and drag forces. Following this, we will understand the concept of pressure-driven internal flows as we examine the famous Couette and Poiseuille flows. Finally, we will use Ansys Fluent to simulate some practical engineering flows to gain a deeper understanding of internal and external flows.
