Radiation Transfer Phenomena Chapter 8b: Radiation

This lecture covers the absorption coefficients of water and CO₂, the emission and absorption factors in radiation exchange, the concept of emissivity, and the exchange of heat by radiation between different surfaces. It also discusses the emissivity correction term, the law of Kirchoff, and examples of radiation. The lecture delves into the complexities of heat exchange through radiation, including the interactions between multiple bodies and the modeling of simplified systems to analyze the net radiation exchanges. Additionally, it explores the factors affecting the absorption and emission of radiation by opaque surfaces separated by a transparent medium, providing insights into the flux densities and angles involved in these processes.
