Introduction to modes of heat transfer and applications in biochemical engineering operations including sterilization and heat inactivation. Heat transfer by conduction, convection and radiation, heat transfer during boiling and condensation. Unsteady state heat conduction in solids, response time of thermocouples. Fourier’s equation: analytical and numerical solutions, chart solutions. Worked examples. Unsteady state heat convection – cooling and heating of bioreactors – worked examples and case Studies Heat transfer with a phase change, condensation and boiling. Modes of condensation – film-wise condensation, Nusselt’s equation, laminar and turbulent flow condensation over flat plates, vertical and horizontal tubes, condensation over a bank of tubes and inside tubes. Radiation heat transfer – simple treatment, black body radiation. Simple heat exchanger design.
