This is very helpful, thanks.
Just wondering though about the absorbing face.
''Let's make the very crude (and optimistic) assumptions that the absorbing surface is 100% absorbing at all wavelengths,''
How would i find out how absorbing the face is across the different wavelengths but...
I'm only looking at the radiative transfer.
The absorbing face will be located approximately between 10 - 25mm away from the skin and in front of the face.
The area of skin (the face) is quite a bit larger than the absorbing surface and located quite close for my application so going by what...
Many thanks again,
What would you estimate the range of heat absorption from skin radiation? i.e. How far away could i have the metal away from the skin before the heat absorbed from radiation be negligible?
I know this has a lot of variable so let's just say that the atmosphere is at 10°C...
Thanks for that.
I want to conduct the heat away. Does this mean that i could coat the conductive material [eg. silver (ideally) or copper (most likely)] with some form of a matt black paint.
Hi All,
I am currently investigating a method of absorbing heat from radiation. This is being done to harness heat from skin.
I was wondering what was the best method to do this?
Is there a particular material that is best suited to do this? I know that having the emissivity value of the...
