In engineering, viscosity is an essential component. But it is not the only one. In this course, we will look “beyond viscosity” and introduce some complex aspects of fluid dynamics which are necessary to understand real-world engineering applications. First, we will discuss fluid compressibility in the lesson “Elements of Compressible Flows.” Next, we will introduce the concept of “Heat Transfer” and learn about the three different modes that facilitate the transfer of heat in engineering. Finally, we will understand and analyze “Flows with Moving and Rotating Objects.”
