Windows and Coatings: Heat Transfer

This lecture covers the principles of heat transfer in windows and coatings, focusing on minimizing reflection and optimizing absorption. Topics include non-absorbing and absorbing coatings, refractive index of common coatings, and the use of dielectric coatings to reduce reflection. The lecture also delves into the concepts of thermal conductivity, energy conservation equations, and the balance of scalar quantities. Various methods for solving heat transfer problems, such as Fourier's law and the advection-diffusion equation, are discussed. The importance of effective conductivity in heterogeneous media and the analytical and numerical solutions for transient conduction are also explored.
