Outline and Purpose of the Course This course focuses on the heat transfer phenomena at the foundation of heating, cooling, and insulation techniques, that is heat conduction, convection heat transfer, and thermal radiation. With respect to heat conduction, we will discuss the steady-unsteady phenomenon and the theory of extended surface heat transfer. With respect to convective heat transfer, we will discuss single-phase forced convection/natural convection and the boiling and condensation transfer accompanying phase transitions. With respect to thermal radiation, we will discuss the basic theory.
Course Goals Provide basic knowledge and deepen understanding of heat transfer phenomena (heat conduction, convective heat transfer, thermal radiation).
Schedule and Contents (1)
General information: Based on multiple examples of energy conversion requiring heating, cooling, and insulation techniques, and temperature control of equipment, explain the importance of heat transfer engineering and the basic mechanisms of heat transfer phenomena.
(2-4)
Heat conduction: Explain the basics of heat conduction phenomena, specifically heat flux, thermal conductivity and Fourier’s law, and the derivation of the equation of heat conduction, with reference to basic case examples. Explain thermal contact resistance, steady heat conduction, and heat conduction resistance in flat plates, pipes, etc., the theory of extended surfaces (fins), and so on.
(5)
Basic information on convective heat transfer: Formularize the governing equations of flow in heat transfer. Explain dimensionless numbers such as Prandtl number, Nusselt number, Stanton number, Grashof number, and Rayleigh number. Derive the momentum and energy equations for the boundary layer flow and heat transfer.
(6-9)
Convective heat transfer without phase change: Explain specific examples of forced convective heat transfer, as well as general information. As examples of external flow heat transfer, explain laminar and turbulent boundary layer flow over a flat plate accompanying heat transfer. Also, as an example of internal flow heat transfer, explain heat transfer of flows within tubes. Also, explain natural convection along a vertical heated plate.
(10, 11)
Convective heat transfer accompanying phase changes: With respect to boiling heat transfer, explain the boiling curve in pool boiling and nucleate boiling, transition boiling, film boiling heat transfer mechanisms, and the effects of various factors that affect nucleate boiling heat transfer and methods to enhance heat transfer. With respect to condensation heat transfer, explain the difference between dropwise condensation and film condensation, phenomena in condensation interfaces, and the Nusselt solution in vertical plate film condensation.
(12-14)
Radiation heat transfer: Discuss black bodies and gray bodies, Kirchhoff’s law, Planck’s law, and Wien’s displacement law, Stefan-Boltzmann’s law, radiation transfer between black body surfaces and radiation in actual surfaces, and the properties of radiation in gases.
