The Ansys Innovation Space website recently experienced a database corruption issue. While service has been restored there appears to have been some data loss from November 13. We are still investigating and apologize for any issues our users may have as a result.
Heat Transfer in Fluids
From power generation to HVAC systems, from electronics cooling to food preparation, heat transfer is everywhere. In fact, heat transfer facilitates the existence of life on our planet. In this learning track, we will explore the fundamentals of heat transfer in fluid flows. We will begin by looking at the three different modes of heat transfer - conduction, convection, and radiation. We will then go over some key concepts in thermal conduction before moving to a detailed discussion on convection. We will discuss forced convection in both internal and external flows and learn how heat exchangers work. We will wrap up the learning track by going over natural convection. Alternate video link.

Intro to Heat Transfer in Fluids
From HVAC systems to electronics cooling, from power generation to food preparation, heat transfer is everywhere. In fact, the very existence of life on Earth depends on the heat from sun. The process of heat transfer occurs between two systems that are at differe...Read more

Forced Convection in External Flows
Forced convection heat transfer refers to a process in which fluid flow generated by external means, such as a fan or an externally imposed pressure gradient, extracts or imparts heat from or to objects at temperatures different from the flow temperatures. Forc...Read more

How Heat Exchangers Work
Forced convection is a critical phenomenon in many engineering applications involving heat and mass transfer. The fluids are forced to flow through pipes and ducts to accomplish the desired transfer of thermal energy. For such applications the friction at the walls create...Read more

Natural Convection
Have you ever wondered how a cup of hot coffee cools down when you leave it on a table? Even though there is no external forcing, convection heat transfer still occurs due to the convection currents that exist within the ambient air owing to density gradients. This is referred ...Read more
