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, 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.

Course Objectives

  1. To enable the students to understand the basic heat transfer mechanisms, performance of evaporators and heat exchangers.

Course Outcomes

? Enable to demonstrate general knowledge of heat transfer [conduction, convection, radiation], and mass transfer [molecular diffusion, convection].
? Enable to define and solve steady-state and transient problems in 1-D and 2-D .
? Enable to design heat and mass transfer processes and equipment.
