If you have a link to your brothers work i'd love to read it and i'm sure my FIL would too.
Hey DB,

Here's what my brother had to say when I asked about his paper.......

I think what you're referring to is probably my Ph.D. work. I did a study of the effects of bouyancy on turbulent jet flames in a crossflow. That's when you have a fuel stream runninhg out into a stream of air that blows it to one side. Most people assume that bouyancy is negligible in such a flame but before my work, there was no rigorous analysis of when such an assumption is appropriate. My dissertation looked at developing a way to determine when this effect is significant enough to be considered and provide a way for others to make that decision.

The reason most people neglect this is because it's a giant pain in the ass to deal with from a mathematical standpoint. If I'd known how hard it would be to find a parameter to quantify the effect, let alone determine what value the parameter should have, I'd have chosen something else to work on. I pulled it off though. Was a neat bit of work.

Hope you find it interesting.

P.S: The bold emphasis is mine because I thought that remark was very pertinant to the recent discussion. re: fitting data to the theory, problems with modelling etc.
