Thermal Transfer Fundamentals

This lecture covers the basic principles of thermal transfer, including the first and second laws of thermodynamics, heat transfer mechanisms (conduction, convection, and radiation), and the thermal evolution. It delves into topics such as the conservation of energy in closed systems, the increase of total entropy in thermodynamic processes, and the different ways heat is transferred. The lecture also explains the concepts of stationary and non-stationary regimes, Fourier's equation, and simplifications of this equation. Additionally, it explores examples of thermal conduction, the role of temperature gradients, and the conductivity of various materials.
