Thermal Animation of a Sapphire Refractive Secondary in Orbit
(Click on picture to see animation)
A transient thermal model is used to predict
temperatures and thermal gradients in a system composed of a
Refractive Secondary Concentrator integrated with the Shooting
Star solar thermal engine. The analysis is invaluable in determining
the operating conditions and materials requirements for the refractive
secondary concentrator.
- Temperatures are in degrees Celsius, and
time is in seconds
- Initial temperature of the refractive secondary
is 23 C
- Animation shows 2.5 orbits - an orbit is
defined as 60 minutes on-sun followed by a 30 minute eclispse
- A yellow circle will be displayed on the
right edge of the animation to indicate on-sun periods
