Thermal Engineering is an Android application designed for mechanical engineering students. Developed by Engineering Hub, this free app provides notes on thermal engineering and gas dynamics. The app covers all the essential topics in thermal engineering with graphics in a chapter-wise manner.

The app consists of five chapters. Chapter one covers steam generators and includes topics such as steam generator classification, conventional boilers, high-pressure boilers, combustion in boilers, and many more. Chapter two deals with phase change cycles, including topics like the Rankin cycle, modified Rankin cycle, and regenerative-reheat cycle. Chapter three covers gas dynamics, including topics such as the speed of sound, mach cone, mass flow rate, and flow of steam through nozzles. Chapter four is all about air compressors and covers topics like compression processes, volumetric efficiency, and classification and working of rotary compressors. Finally, chapter five covers steam condensers, cooling towers, and heat exchangers.

Overall, Thermal Engineering is an excellent resource for students who want to learn about thermal engineering and gas dynamics. The app is easy to use and provides comprehensive notes on all the essential topics. The graphics used in the app are also helpful in understanding the concepts better. However, the app could benefit from more interactivity and quizzes to test the users' knowledge.
