Previously I taught thermofluids to 1st year mech,aero,civil,ship and acoustics engineering students and wrote a textbook for them. The text includes chapters that cover most of most engineering degrees in years 1 and 2. More focus is provided in year 1 content. In contrast to the research monographs I retained the copyright and self published it. It is still available here, though I would note that it does not include examples and problems, these were supplied in house as part of the university course provision. I plan to revise this textbook and include these things to create a more standalone product.
There were also a set of lectures that were recorded that link directly to this textbook. The slide deck is here. The following table lists the subjects of each of the videos and provides links to the location of the videos.
