Introduction to the Phenomenon of Transmission
Thread Content
The school is going to offer this course~~ I’d like to ask those who are more experienced what the role of this course (which is also called transfer processes in some schools) is within the overall curriculum of the chemical engineering program. Are there any key points that should be focused on when studying this course?
The “three transfers and one reaction” in chemical engineering includes transfer processes, so its importance is evident. However, the theory behind transfer processes is quite complex, requiring a strong foundation in mathematics.
This is the first time I’ve heard of it. Judging from the name, it must be a quite specialized course.
An introduction usually covers only basic knowledge, right? There is a lot related to partial differential equations in the principles of transmission processes, so it does require a higher level of mathematical knowledge.
The transfer process is the common foundation of unit operations and reaction engineering. The physical processes that take place in various unit operation equipment and reaction vessels are nothing more than three types of transfer: momentum transfer, heat transfer, and mass transfer. For example, fluid transport based on momentum transfer, gas flow distribution in reactors ； Heat exchange operations based on heat transfer, such as the removal of polymerization heat from polymerization reactors; absorption operations based on mass transfer, such as the diffusion of reactants and products within the catalyst. In some processes, two or more types of transfer phenomena occur simultaneously, such as moisture addition and removal in gases. As a branch of chemical engineering, transport processes focus on studying the rates of these three types of transport as well as their interrelationships, thereby linking together phenomena that are essentially similar but exhibit different forms.
