Understanding Solar Radiation.
It is important to understand the source of all solar energy which off course is the sun. Solar energy is responsible for fueling all life on planet earth and is the source behind all forms of solar power as well as wind and biofuel energy. As a student of solar energy understanding solar radiation seems fundamental in nature.
The lecture was based on the textbook of Cengel and Ghajar (4th edition) and was presented as part of a heat transfer class to the fourth year students of the Department of Mechanical and Aeronautical Engineering by Prof Josua Meyer, Head of the Department of Mechanical and Aeronautical Engineering of the University of Pretoria, South Africa. Lecture was presented on 15 September 2014.
This lecture continues with radiation but the focus shifts to atmospheric and solar radiation. The properties of the sun are considered and the surface temperature of the sun is calculated using the solar constant. The spectral distribution of the solar radiation on the ground is considered as well as the scattering in the atmosphere (diffuse radiation).
A few simple solar radiation problem are addressed.
I hope you enjoy this free solar radiation energy lecture.
