Nicholas Worth
Background and activities
My research is aimed at increasing our fundamental understanding of different fluid flows in order to better predict and control them. Currently I have a focus on thermoacoustic instabilities in gas turbine combustors, the small-scale structure of high Reynolds number turbulence, and the development of new experimental methods.
