The What, Why and How of Simulating Joule Heating
Thursday, February 11, 2016

Any device that uses electrical power experiences energy loss to heat. A primary physical phenomena causing this is known as Joule (or ohmic or resistive) heating, and it can be either advantageous or detrimental for a given system.

Some applications - such as fuses, floor heaters, heat lamps, and window defrosters - rely on Joule heating for their operation. In other applications - including bus bars and high-power printed circuit boards - Joule heating is an inevitable side effect that must be predicted and managed if the product is to perform reliably.

This webcast explores the physical phenomena of Joule heating and present standard calculations that can be used to predict the amount of heat dissipated based on the electrical situation and conductor material. In addition, options for modeling Joule heating in engineering simulation is shown through examples, including a discussion of the different advantages and disadvantages.
