The Efficient Engineer - Understanding Thermal Radiation, 30112021

This video looks at thermal radiation, one of the three modes of heat transfer along with conduction and convection. It starts by covering electromagnetic waves, the Stefan-Boltzmann law, black bodies and emissive power. It then talks about emissivity, absorptivity, transmissivity and reflectivity, as well as views factors, all key concepts for being able to calcualate the radiative heat transfer between surfaces
