2022

This semester we are continuing to perform research for DARPA on analytical methods for hypersonic aerodynamics. It is a difficult task. My new students are transitioning well and former students are excelling in their new careers. I am teaching a new course on turbulence modeling. This should be placed online for everyone near the end …

Foundations of Turbulence

The mathematical formulation of the problem of homogeneous turbulence is this: Given an infinite body of uniform fluid in which motions conform to the equations and, and given that at some initial instant the velocity of the fluid is a random function of position described by certain probability laws which are independent of position, to …

Andrei Nikolaevich Kolmogorov – A Digital Tribute

http://kolmogorov.com The great Academacian Andrei Nikolaevich Kolmogorov, who pioneered turbulence theory and started the Russian school, has fans overseas (big surprise!). I always wanted to create a website with a collection of his pictures, portraits, important articles, and anything else I could find online or off. Someone of course beat me to it! A recommended …

HiFiLES High Fidelity Large Eddy Simulation

https://hifiles.stanford.edu/ My students and myself were impressed with the Stanford University release of HiFiLES, a large-eddy simulation solver for turbulent flows. We were able to use it successfully in our Office of Naval Research Grant. In fact, our modifications were released for free with an in-built acoustics solver. These codes are free of charge to …
