Fundamentals of radiative heat transfer and its applications. Examples are combustion and solar thermal/thermochemical processes, and other applications in the field of energy conversion and material processing.
Content
1. Introduction to thermal radiation. Definitions. Spectral and directional properties. Electromagnetic spectrum. Blackbody and gray surfaces. Absorptivity, emissivity, reflectivity. Planck's Law, Wien's Displacement Law, Kirchhoff's Law.
2. Surface radiation exchange. Diffuse and specular surfaces. Gray and selective surfaces. Configuration factors. Radiation exchange. Enclosure theory, radiosity method. Monte Carlo.
3.Absorbing, emitting and scattering media. Extinction, absorption, and scattering coefficients. Scattering phase function. Optical thickness. Equation of radiative transfer. Solution methods: discrete ordinate, zone, Monte-Carlo.
A repetition date will be offered in the first two weeks of the semester immediately consecutive.
Additional information on mode of examination
Open-book, 2-hour, written exam during the last week of the semester. Learning task: Monte-Carlo programming project is optional. If completed and handed in, it can improve the total course unit grade by 0.25 grade points.
