3D Thermal Data?
3D Thermal Data?
(OP)
I'm completely new to thermography. I'm involved in a project that where we're introducing a heat source into the center a cube-shaped medium. We need to record the migration of the heat in all directions from the source over a fixed time interval (2-3 minutes).
The ideal end result would be an animation that models the heat flow in real time.
Can this be done using IR? It's beyond me, ultimately we'll be looking to find an experienced 3rd party to consult on this I'm just at the stage of determining the feasibility of what we're trying to do. I'm hoping those with more experience will chime in with their feedback.

Your best bet might be a miniature RTD or thermocouple. Page 7 of http://www

RE: 3D Thermal Data?
It might be an area better suited to computer simulation. If the medium is a liquid or gas you could try using CFD (Computational Fluid Dynamics). I'd also asume that there would be less work involved to turn this into a 3D animation.
There are various companies that specialise in this sort of thing.
RE: 3D Thermal Data?
There has been some mathematical modeling done for a similar study, however there's enough difference that we can't conclude it will apply to our situation.
We did consider using an array of RTD's to measure the temperature, however it will take quite a few to achieve a decent 3-dimensional resolution, and we'd need to build a support framework for them to ensure a controlled physical location over multiple trials. Ultimately this may be the direction we pursue if there isn't a more "off the shelf" approach.
RE: 3D Thermal Data?
I would look for symmetries and apply RTD's in anticipation of the symmetries of the setup to minimize the number of devices.

RE: 3D Thermal Data?
Do you anticipate that the heat transfer through the voids in the matrix is a significant contributor?
IR could be used to monitor the outside of the cube to validate the simulation results from FEA or CFD.
I would be glad to discuss this further with you. Feel free to contact me through my website.
