Shell and Tube Heat Exchanger (3D)

The dreadful subject in my college was none other that process equipment design where as the name suggest we had to design several chemical process equipment. One reason why I hated that subject was the way it was taught to us which I don’t think has been changed in centuries. Same old books, same old theory and same old diagrams. Everything was an absolute disaster to me. The book D.Q. Kern which I brought with so much of interest had me going bananas in some chapter particularly heat exchangers. So now here is my suggestion for students and professors who are teaching that course, please teach with the help of a model which can be real or virtual (like the one give below).

Though this model may not be the most accurate heat exchanger in the world it does convey some sense of visual understanding to the student who is learning the subject for the very first time. I still remember when even after completing the preliminary course of Process Equipment Design people had no idea about this called Baffles. On one hand the design baffled us and on the other hand equations took a toll on us that’s the reason why I called it the most dreadful subject in my college. This model will not help you with mathematics but will give some sort of idea about the construction of the internals and outer structure of STHE.

So without wasting any time lets straight away jump to the 3D model. Ladies and gentlemen I present thee the 3D model of Shell and Tube Heat Exchanger.
