optical thickness
Hey there!
If you simulate radiation, u need to know the so called optical thickness. Can someone help me with this? For example i want to calculate the optical thickness of a air-film with 10mm thickness. Thx a lot! |
google wiki optical thickness air

Hi!
I searched google up and down and found nothing, thats why i asked my question in this forum! By the way the first entry in google is this post in this forum here ;-). Can you gibe me better tipps? Thx a lot! |

http://en.wikipedia.org/wiki/Optical_depth I think you'd probably need to visit your university library borrow a physics book and read it. especially the bits that refer to wavelength :cool: Quote:

Quote from Wiki:
"One way of visualizing optical depth is to think of a fog. The fog between you and an object that is immediately in front of you has an optical depth of zero. As the object moves away, the optical depth increases until it reaches a large value and the object is no longer visible." Means air always has optical thickness of 0? I just wonder about the fact that in this forum so many people simulate radiation and the optical thickness seems to be the significant parameter to choose the radiation modell. So there must be a paper where you could get those values. but i dont find anything...why? |
before even touching cfx you need to understand the basic principles and what you want to do.
here's a link to read as I still think that you have some more reading to do anyway in cfx there are a few different radiation models to chose from. the manual has all the information you need to describe how these radiation models work. |
