Fall 2023
Who would have thought that 7 years go by so quickly at the University of Florida. This year I am teaching introduction to computational fluid dynamics. The last time I taught it was before COVID in the fall of 2020. I am working on a new design program for nozzles. I am basing it on …

The New Colossus
Not like the brazen giant of Greek fame,With conquering limbs astride from land to land;Here at our sea-washed, sunset gates shall standA mighty woman with a torch, whose flameIs the imprisoned lightning, and her nameMother of Exiles. From her beacon-handGlows world-wide welcome; her mild eyes commandThe air-bridged harbor that twin cities frame.Keep, ancient lands, your …
Congratulations to my Students at the MAE Awards 2023
Additional Thoughts on Pressure
I am obsessed with pressure, particularly the internal pressure of fluids. Unlike viscosity, it is absent of frictional forces, and it is a key driving force in both human behavior and aerospace flows. Pressure is an essential component of a perfect fluid and appears on the right-hand side of the Navier-Stokes equations. Without pressure, fluid …
Spring 2023 Semester
It’s the start of a new semester, and I’m excited to welcome a new group of students to the Theoretical Fluid Dynamics and Turbulence Group. This semester, we have a diverse group of students working on a range of interesting projects. Christian King, who joined us in May 2021 as a Ph.D. student, is studying …
Associate Professor
It is my first day as an Associate Professor of Mechanical and Aerospace Engineering at the University of Florida. Just about six years ago I left NASA and joined as an Assistant Professor. My goals remain the same. First is to perform excellent research of fundamental nature. The second is to inspire others and myself. …
Thomas D. Norum
My good friend Thomas D. Norum recently passed away. He worked as a researcher at NASA Langley over most of his career. I knew him starting in 2009 through 2016 while I was working there. He worked as an experimentalist in the jet noise lab of NASA Langley. As an experimentalist, he worked to understand …
Variable Density Wind Tunnel
When visiting NASA Langley I had Josh Blake kindly take my picture by the Variable Density Wind Tunnel. Pioneered by Max Munk, leading theoretician in aerodynamics in America in our early years of aviation. National historical landmark: The test section and airflow passages built into the VDT pressure vessel formed a continuous flow of pressurized …
