Transport Processes: From Classical Laws to Nanoscale Effects

Heat and energy flow govern almost every system, from microchips to power plants. Understanding how transport mechanisms change drastically between the macroscopic world and the nanoscale is crucial for modern engineering. This course provides a rigorous, text-based foundation in transport processes, focusing on the fundamental physics that dictates how energy carriers—photons, electrons, phonons, and molecules—move and interact. You will gain the descriptive tools necessary to analyze energy transfer problems across vast differences in scale. What you'll learn: * Understand the statistical behavior and internal energy of key energy carriers: photons, electrons, and phonons. * Apply the principles of classical thermodynamics and fluid dynamics to describe macroscale heat and mass transport. * Analyze wave and particle transport mechanisms, including scattering, generation processes, and their impact on energy flow. * Derive and interpret the Boltzmann transport equation as the core framework for non-equilibrium transport modeling. * Examine how transport phenomena deviate from classical laws when operating at the nanoscale and microscale. * Practice conceptualizing basic computational methods used for modeling complex thermal behavior in modern materials. The course begins with an introduction to energy carriers and statistical mechanics, transitioning into classical transport laws before deeply exploring the complexities of nanoscale phenomena, the Boltzmann equation, and modern applications. Through detailed written explanations and practice exercises, you will build a robust theoretical framework. This course is designed for absolute beginners in mechanical engineering, physics, or materials science. No prior advanced knowledge of statistical mechanics or quantum physics is assumed.
