Enlightenment of Mass Transfer on Heat Transfer Teaching in Teaching of Principles of Chemical Engineering and Its Application
Abstract:
The common points of absorption and heat transfer were found by comparison of the assumptions and transfer model. Furthermore, the computational formula and graphs of the number and the length of a transfer unit were deduced in the countercurrent heat transfer through learning from the treatment method of absorption. Based on the study, the basic analysis methodology for qualitative analysis of operational heat transfer problems was proposed. The connection between mass transfer and heat transfer was established through the comparison, so that they were no longer random knowledge points, which was beneficial for students to understand and master principles of chemical engineering.
