Transport Phenomena

2nd Edition (Note that the first edition was 1960!)

Course Description: Thermodynamics tells us if a transformation or process can be expected to occur.  Transport Phenomena, often tells us how fast it will occur.  In the first semester of the course, momentum transfer was the primary topic.  This semester the topics will be heat transfer and mass transfer.  Generally the focus will begin with the fundamental equations of transport on the microscale (with large continua of molecules, but smaller than any geometric scale of the system), which are then integrated to describe macroscopic problems.  The physics of the problems and the mechanisms described by the solutions are emphasized, but there is a need to understand the basic mathematics of the solution procedures.  Considerable effort will be spent on developing a strong understanding of transport processes so that the ideas can be applied to the many different systems that students will encounter, when they are no longer students.
