This course assumes that the students have undergone UG courses in Engineering
Mathematics, Thermodynamics, Heat Transfer and Fluid Mechanics and are familiar with
the use of experimentally derived CORRELATIONS for estimating heat/mass transfer
coefficient in a variety of flow situations. The purpose of this course is to justify the basis
and the form of these correlations on the basis of fundamental transport laws governing
The treatment is highly mathematical and, through assignments,
students are expected to formulate and solve problems to derive expressions for the
heat/mass transfer coefficient in different situations. The course will interest students
wishing to embark on a research career in heat/mass transfer.
