AIM
To provide fundamental instruction in various methods of heat transfer through difference
media. To impart knowledge on how certain substances undergo go the change in
composition, change in phases and exhibit the properties according to the changed
environment.
OBJECTIVES
Students gain knowledge in various heat transfer methodology in chemical process
engineering. Also students develop a sound knowledge in Mass Transfer operation.
UNIT I 9
Introduction to various modes and mechanisms of heat transfer. Fourier’s law of heat
conduction – one dimensional steady state heat conduction equation for flat plate, hollow
cylinder, rate equations, Heat conduction through a series of resistances – Thermal
conductivity measurement, effect of temperature on thermal conductivity. Difusional heat
transfer based on shell balances approach for one-dimensional steady state and transient
transfer with heat generation and chemical reactions. Composite walls, heat transfer in
extended surfaces.
25
UNIT II 9
Concepts of heat transfer by convection – Natural and forced convection, analogies between
transfer of momentum and heat transfer. Reynold’s analogy, prandtl and coulburn analogy.
Dimensional analysis in heat transfer. Correlations for calculation of heat transfer coefficients,
heat transfer co-efficient for flow through a pipe.
Heat transfer to fluids with phase change – heat transfer from condensing vapours, dropwise
and film wise condensation, Nusselt equation for vertical and horizontal tubes, effect of noncondensable
gases on rate of condensation.
UNIT III 9
Paraplel and Counterflow heat exchangers – Log mean temperature difference – single pass
and multipass heat exchangers, plate heat exchangers. Fouling factors design of various
types of heat exchangers.
UNIT IV 9
Diffusion in fluids – Molecular and eddy diffusion measurement and calculation of diffusivities.
Ordinary diffusion in multi component gaseous mixtures.
Mass Transfer co-efficients. Theories of mass transfer, concept of NTU & HTU. Analogies
between momentum, heat and mass transfer. Equilibrium and operating lines. JD factor.
Liquid – Liquid Equilibrium – Extraction principles – Batch and continuous extractors – Design
equation for extraction. Spray, packed and mechanically agitated contactors and their design
calculations – packed bed extraction with reflux.
UNIT V 9
Vapour liquid equilibria – Raoult’s law, Vapor liquid equilibrium diagrams for ideal and nonideal
systems, enthalpy concentration diagrams. Principles of distillation, flash distillations,
differential distillation, steam distillation, multistage continuous rectification, number of ideal
stages by Mecabe – Thiele method panchan – Savarit method. Total reflex, minimum reflex
ratio, optimum reflex ratio. Multicomponent distillation. Areotropic and extractive distillation.
TOTAL: 45 PERIODS
