Professor Obert has observed in his famous treatise on Thermodynamics that concepts are
better understood by their repeated applications to real life situations. A firm conviction of
this principle has prompted the author to arrange the text material in each chapter in the
following order.
In the first section after enunciating the basic concepts and laws mathematical models
are developed leading to rate equations for heat transfer and determination of temperature
field, simple and direct numerical examples are included to illustrate the basic laws. More
stress is on the model development as compared to numerical problems.
A section titled “SOLVED PROBLEMS” comes next. In this section more involved
derivations and numerical problems of practical interest are solved. The investigation of the
effect of influencing parameters for the complete spectrum of values is attempted here. Problems
involving complex situations are shown solved in this section. Two important ideas are stressed
in this section. These are checking of dimensional homogeneity in the case of all equations
derived and the validation of numerical answers by cross checking. This concept of validation
in professional practice is a must in all design situations.
In the next section objective type questions are given. These are very useful for
understanding the basis and resolving misunderstandings.
In the final section a large number of graded exercise problems involving simple to
complex situations are included.
In the first of the 14 chapters the basic laws for the three modes of heat transfer are
introduced and the corresponding rate equations are developed. The use of electrical analogy
is introduced and applied to single and multimode heat transfer situations. The need for iterative
working is stressed in the solved problems.
The second chapter deals with one dimensional steady state conduction. Mathematical
models are developed by the three geometries namely Plate, Hollow Cylinder and Hollow Sphere.
Multilayer insulation is also discussed. The effect of variation of thermal conductivity on heat
transfer and temperature field is clearly brought out. Parallel flow systems are discussed.
Examples on variation of area along the heat flow direction are included. The use of electrical
analogy is included in all the worked examples. The importance of calculating the temperature
gradient is stressed in many of the problems.
In the third chapter models for conduction with heat generation are developed for three
geometric configurations namely plate, cylinder and sphere. The effect of volume to surface
area and the convection coefficient at the surface in maintaining lower material temperature
is illustrated. Hollow cylindrical shape with different boundary conditions is discussed.
Conduction with variable heat generation rate is also modelled.
