WebTools. Concentric Tube (or Pipe) Heat Exchangers are used in a variety of industries for purposes such as material processing, food preparation, and air-conditioning. [1] They create a temperature driving force by passing fluid streams of different temperatures parallel to each other, separated by a physical boundary in the form of a pipe. WebIn this video you will learn how to create expressions to calculate overall heat transfer coefficient in Ansys CFD Post.This is a follow-on video from a prev...
