Recommendations for introductory texts on turbomachinery are sought, particularly for someone with a background in fluids, thermodynamics, and heat transfer in the aerospace industry. The current book being read is criticized for assuming too much prior knowledge about turbines and compressors. There is a consensus that no single book is universally recommended, as proprietary knowledge specific to companies plays a significant role in training and expertise. The discussion highlights that while aero and fluids knowledge is relevant, the majority of turbomachinery work involves mechanical design. Overall, finding a suitable introductory text remains a challenge due to the specialized nature of the field.
