Hi all! I defended my Ph.D. thesis back in 2019 and I also served as the creator and moderator for the subreddit r/FluidMechanics for a long time. I think with that I have gathered enough experience and courage to answer some of your queries. Some broad topics that I can answer questions on are:

  • computation fluid mechanics
  • scientific programming and HPC
  • nonlinear shallow water equations
  • statistical description of turbulence: spectra, energy budget etc.
  • experimental methods: PIV
  • stratified turbulence
  • academia
  • navigating your career pre- and post-Ph.D.

Ask away!

    Every orifice adds some drag into the flow, decreasing the flow rate. However if you would go for a descending size of orifices you would introduce a Venturi effect, increasing the velocity for a given flow rate. Think what happens when you squeeze the end of a gardening water hose; or what happens when you blow air out of your mouth.
