Thermofluids while a relatively modern term is applied to the well-established field of
thermal sciences which is comprised of various intertwined disciplines. Thus mass momentum
and heat transfer constitute the fundamentals of th- mofluids. This book discusses thermofluids
in the context of thermodynamics single- and two-phase flow as well as heat transfer
associated with single- and two-phase flows. Traditionally the field of thermal sciences is
taught in univer- ties by requiring students to study engineering thermodynamics fluid
mechanics and heat transfer in that order. In graduate school these topics are discussed at
more advanced levels. In recent years however there have been attempts to in- grate these
topics through a unified approach. This approach makes sense as thermal design of widely varied
systems ranging from hair dryers to semicond- tor chips to jet engines to nuclear power plants
is based on the conservation eq- tions of mass momentum angular momentum energy and the
second law of thermodynamics. While integrating these topics has recently gained popularity it
is hardly a new approach. For example Bird Stewart and Lightfoot in Transport Phenomena
Rohsenow and Choi in Heat Mass and Momentum Transfer El- Wakil in Nuclear Heat Transport
and Todreas and Kazimi in Nuclear Systems have pursued a similar approach. These books however
have been designed for advanced graduate level courses. More recently undergraduate books
using an - tegral approach are appearing.
