AI Thread Summary
To compute the total reflected solar radiation from a parabolic trough to its focal point, one must consider the geometry of the trough, the mirror's reflectivity, and the incident solar irradiation. The discussion emphasizes the importance of understanding insolation, which varies based on factors like latitude and time of day. A detailed procedure for calculating radiation transfer between the mirror and focal point is sought, rather than just information on incident solar radiation. Suggestions for relevant books, software, or websites to aid in this calculation are also requested. The conversation highlights the need for precise methodologies in solar energy applications.

Hi to everyone

I wonder if someone knows how can i compute the total reflected solar radiation from a parabolic trough aperture area to the focal point, if we know the geometry of the parabolic trough the reflector coefficiency of the mirror and the amount of solar irradiation that is incident on the concentrator in a direction parallel to the central plane of the parabola. I would appreciate very much if someone could help me because i need this information in order to complete an essay that I'm working on.

Relevant books, software or web sites are welcome.

Thanx everyone in advance

Look up 'insolation'. It's the amount of solar radiation per unit area per unit time. It's a function of latitude, time of day, etc...even altitude. Try average insolation as well.

I've already found a lot of things about the amount of incident solar radiation. What I am asking is a procedure to calculate the radiation transfer between a parabolic mirror and its focal point, if iknow the insolation and the reflection of the mirror.

Thank u
 
Anyone?
 

Thread 'Off resonance driving of a MW/RF cavity'

Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
