Syllabus

Mechanism of heat transfer: Conduction– Fourier s law, Steady state conduction of heat through plane, cylindrical and Spherical solids - single and in series.

Convection– Steady state heating and cooling of fluids without phase change, Critical thickness of insulation, Lumped capacitance model, Heat transfer from condensing vapours and––to boiling liquids filmwise and dropwise condensation, boiling coefficients.

Radiation Kirchhoff s law, Stefa -Boltzman law, Simple case of radiation heat transfer between surfaces

Applications of heat transfer: Evaporation Effect of liquid characteristics, Single and multi- effect evaporation, Types of evaporation and their attachments,

Performance of single effect evaporation, Boiling point rise, Multiple effect evaporation – forward, backward, mixed and parallel feed, Performance of multiple effect evaporation in comparison to that of single effect evaporation, Vapour compression evaporation, Calculations for single effect evaporators Different types of Heat Exchangers Heat transfer augmentation

Learn the basic principles and laws governing the three modes of heat transfer: conduction, convection, and radiation

Solve steady-state and transient heat transfer problems in various geometries like flat plates, cylinders, and spheres

Use empirical correlations and dimensionless numbers to evaluate forced and free (natural) convection systems

Estimate heat transfer rates and size practical thermal equipment, specifically heat exchangers and evaporators

Enable to apply basic laws governing conduction, convection, and radiation. This includes Fourier's law, Newton's law of cooling, and the Stefan-Boltzmann law

Students develop knowledge in steady-state and unsteady-state (transient) heat conduction problems across various geometries like flat plates, cylinders, and spheres

Enable students to determine individual and overall heat transfer coefficients for laminar and turbulent flows, using dimensionless numbers and empirical correlations

Estimate heat transfer rates for boiling and condensation, and analyze radiation exchange between different black and gray surfaces

Enable students to apply basic design principles to size and rate industrial equipment such as double-pipe heat exchangers, shell-and-tube heat exchangers, and evaporators
