2190422 – Heat Transfer and Thermal Fluid Flow
The lecture provides a comprehensive introduction to the fundamental principles governing heat transfer and thermal fluid flow with a focus on the heat transfer modes conduction and convection. The governing equations of continuum mechanics for heat transfer and thermal fluid flow are intro-duced including the balance equations, constitutive relations, and thermodynamic state equations necessary for modelling thermal systems. Steady and transient heat conduction is considered in vari-ous geometries, composite materials and systems with and without internal heat generation. In the area of convection, both external and internal flows are studied. Topics include important dimension-less numbers, boundary layer theory, laminar and turbulent flow behaviour, analytical and empirical heat transfer correlations, and practical applications such as flow over flat plates and through pipes or tube banks. Particular attention is given to flow development, entrance effects, and techniques for enhancing heat transfer. Finally, the fundamentals of thermal radiation are presented, including blackbody radiation, radiative heat flux, and the interaction of radiation with materials through emis-sion, absorption, reflection and transmission. Exercises accompany the lecture to support the appli-cation of theoretical knowledge and analytical tools to real-world situations.
