Notions of Transport Phenomena

Transfer phenomena consists of three related subjects: heat transfer, mass transfer, and fluid dynamics. heat transfer deals with the transport of energy, mass transfer is concerned with the transport of mass of various chemical species, and Fluid dynamics involves the transport of momentum.

These three transport phenomena should, at the introductory level, be studied together for the following reasons:

• They frequently occur simultaneously in industrial problems ;

• The basic equations that describe the three transport phenomena are closely related ;

• The mathematical tools needed for describing these phenomena are very similar ;

• The molecular mechanisms underlying the various transport phenomena are very closely related.
