Calculating Temperature at a distance from a fire.

[Hornet-Wing]

Hi all, I have searched the internet for hours and have come up empty. Perhaps I'm just not entering the correct search terms. What I would like to work out is variation of temperature (in air) with altitude above the fire.

Details:
The fire is a bushfire (a quick search suggests a temperature of 1200C)
Atmosphere temperature being 25C
Altitude above fire 120m

Any ideas how I would go about this task? A rough temperature will be fine.

Thanks for reading!

You might try 'thermal radiation'

There should also be a significant amount of heat rising as a result of natural convection, even at 120 M. Look up natural convection from a horizontal surface.

This is one of those things that you just got to measure.

I'm with Khashishi on this one - there are too many variables, and the physics is too complex to get even a rough estimate.

Check out this web site: http://publications.solar-tower.org.uk/2002_Kroger-Convection%20Heat%20Transfer%20Between%20a%20Horizontal%20Surf.pdf

Convection heat transfer between a horizontal surface and the natural environment

This should give you a reasonable start with your estimate.
