Aerosols in the Industrial Environment

(Or how to bury your work so deeply that no-one will ever know it existed in the first place!)

If there’s one piece of advice I’d give myself as a young researcher, it would probably be “never agree to write a book chapter!”

Of course, there are plenty of good academic book chapters around. But over the years I’ve sadly come to realize that this is the fastest way to make my work inaccessible to people who might otherwise benefit from it — partly because academic books are so expensive that few people can afford to read them!

However, I’ve just come across an even more effective way of ensuring no-one has a hope in hell of benefiting from your research: publishing a chapter in a book which is then dropped from subsequent editions.

The Aerosol Calculator

Back in the late 1990’s, a close colleague and friend Dr. Paul Baron developed the “Aerosol Calculator” — an Excel spreadsheet that contained pretty much every equation imaginable (at the time) related to airborne particle behavior.

The Aerosol Calculator became legend, and an essential tool for anyone working in aerosol science. It contained over 100 equations for calculating aerosol behavior, drawing from the books Aerosol Measurement (edited by Baron and Willeke, and later Kulkarni, Baron and Willeke), and the equally legendary Aerosol Technology by Bill Hinds.

An introduction to aerosol dynamics

Back in the early 2000’s I taught a graduate course at the University of Cincinnati on aerosol dynamics. It was an introductory course that covered the basics of airborne particle physics, including how they behave, what affects this behavior, and how to sample and characterize them.

With the growing coronavirus-inspired interest in face masks and respirators–especially DIY ones–I dug my course notes out, and was surprised at how detailed they are.

And so, just in case anyone’s looking for a crash course in aerosol dynamics, either because they are simply curious, or they want to build a better face mask, here are those notes:

These were written for the class participants rather than for public consumption, and so they are a little clunky in places. And of course, the state of the science has moved on since they were last updated in 2004. Yet the notes still do a surprisingly good job of covering the basics of aerosol behavior in a way that remains relevant today.

UPDATE: One of the key resources for this course was an Excel spreadsheet developed by a good friend and colleague Paul Baron that included an exceptionally comprehensive set of calculations for determining, predicting and modeling aerosol behavior. That “aerosol calculator” can be downloaded here.
