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 original method of characteristics, but integrating boundary layer theory, source plane theory for transonics, and trying to build upon some of the previous programs published by NASA.
