Notice: The Ansys Innovation Space (AIS) will undergo scheduled maintenance from June 6th to June 18th. During this time, all AIS sites will be available in read-only mode with no login function available. This means you will not be able to create any new forum posts on the Ansys Learning Forum, but you can still browse existing ones. Also, the course tracking on Ansys Innovation Courses (AICs) will be unavailable during this period. We apologize for any inconvenience caused.

Real Viscous Flows

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.

Innovation Course

Laminar Boundary Layer Theory

In this course, you will learn about the basics of laminar boundary layer theory. You will explore how to analyze and describe a tiny viscous region that surrounds the body, the boundary layer, and how to estimate the drag acting on the body.

Innovation Course

Basics of Turbulent Flows

In this course, some fundamental aspects of turbulence will be discussed. The concept of laminar-turbulent transition is first introduced, followed by a detailed discussion on what constitutes turbulence. A theoretical framework, including governing equations, to understand turbulent flows is then presented, followed by a discussion on the closure problem and how to deal with it.

Innovation Course

Real Internal Flows

This course provides an overview of internal flows, a branch of fluid mechanics that looks at fluid flows confined by solid walls and their viscous effects. This understanding helps to estimate the losses that an internal passage will develop and enables engineers to design the pumping systems accordingly to sustain the correct flow rate.

Innovation Course

Real External Flows

This course provides an overview of external flows, a branch of fluid mechanics that looks at situations where an object is moving in a fluid or the fluid is flowing over a stationary object. We will begin by analyzing the forces that are exerted by the fluid on the object. We will ...Read more

Innovation Course

Beyond Viscosity

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 comp...Read more
