I updated the YouTube playlists for Compressible flow. There are now two version of the class I taught for almost ten years. The first was recorded live in 2024 in front of an in person and online audience. YouTube Playlist – Fall 2024 Recording The original was recorded in one of my offices and edited extensively. YouTube Playlist Link – Original Recording. The original probably has more material. It is interesting to reflect on teaching improvement between the years they were made. Either way, they are available to the public. The notes and supplemental material remain under classes on this website.
