Introduction to Heat Transfer — Lesson 3

This video lesson defines heat transfer as thermal energy in transit due to a temperature difference in the system of interest. Engineers are interested in the rate of heat transfer and how to optimize it in the devices they build to keep them within an acceptable operating temperature range. This lesson is part of the Ansys Innovation Course: Beyond Viscosity.
