Concepts of heat transfer by convection - Natural and forced convection,
Hydrodynamic and thermal Boundary layers; analogies between transfer of
momentum and heat - Reynold’s analogy, Prandtl and Colburn analogy.
Dimensional analysis in heat transfer, heat transfer coefficient for flow
through a pipe, flow past flat plate.
UNIT III | 9 |
---|
Heat Exchangers – classification and design, overall and individual film
coefficients, mean temperature difference, LMTD correction factor for
multiple pass exchanger, NTU and efficiency of Heat exchangers
UNIT IV | 8 |
---|
Heat transfer to fluids with phase change - heat transfer from condensing
vapours, drop wise and film wise condensation, Nusselt equation for
vertical and horizontal tubes, condensation of superheated vapours, Heat
transfer to boiling liquids - mechanism of boiling, nucleate boiling and
film boiling
UNIT V | 8 |

Evaporation- single and multiple effect operation, material and Energy
balance in evaporators, boiling point elevation, Duhring’s rule. Radiation
heat transfer - Black body radiation, Emissivity, Stefan - Boltzman law,
Plank’s law, radiation between surfaces.
TOTAL: 45 PERIODS
COURSE OUTCOMES: On the completion of the course students are expected
to
CO1: To familiarize the students with the fundamental concepts of Heat
Transfer. Provide the student with knowledge about heat transfer by
conduction in solids for steady state.
CO2: Students will understand convective heat transfer and use of heat transfer coefficients for laminar and turbulent flows.
CO3: The course gives the student insight about boundary layer flow, laminar and turbulent flows.
CO4: Students will be able to calculate and use overall heat transfer coefficients in designing heat exchangers.
CO5: The course provides the student with knowledge about heat transfer with phase change (Boiling and condensation) and evaporation.
CO6: Students will understand radiative heat transfer including blackbody radiation and Kirchoff’slaw, and will be able to solve radiative problems apply knowledge of heat transfer to solve thermal engineering problems
