When the first humans laboriously lit the first fires with the help of flints and tinder in order to warm themselves in or in front of the cave in the evening and grill their meat, fire protection had not yet been invented.
Probably there were also no real smoke extraction concepts using CFD fluid simulation, but the cavemen were dependent on natural conditions.
But I am pretty sure that sitting in the smoke was as uncomfortable back then as it is today.
In a previous blog article, we have already looked at the scanned data of the cave and the surrounding area with regard to rain: (https://www.merkle-partner.de/en/vogelherd-unesco-new-simulation/)
Now we want to have a look at how the natural smoke extraction concept of the Vogelherd cave works.
For those who are not familiar with the local conditions, here is the scan data provided by the State Office for Monument Preservation in the Stuttgart Regional Council.
There you can virtually walk through the cave. A screenshot of the view of the Vogelherd cave from outside is shown in image 2.
The cave has a total of 3 openings, the two entrances (right and left in image 2) and a small channel.
The video clearly shows that the smoke only escapes at the high left entrance, while the right aisle remains largely smoke-free. Fresh air flows mainly through the right corridor and the small duct, while a warming smoke cushion is formed under the ceiling of the main cave and the smoke escapes selectively at one point. We are practically looking at one of the first natural central heating systems of human dwellings.
Warm and smoke-free: maybe this was the reason why mankind had time and muse for the production of the first works of art here of all places? After all, experts estimate the carving time for the creation of the Lion Man to be about 300 hours.
Nowadays, we no longer have to rely on nature to create space, we can design our buildings, be they underground garages, hotel lobbies or congress centers, so that they are properly ventilated, air-conditioned and relatively safe in case of fire.
We are happy to help you with this. Our methods using fluid mechanics are not 40,000 years old, but they have been tested in caves at least as old. ????
Get in touch with me. I will show you in a non-binding conversation how you can benefit from our unique, almost 40 years* old know-how.
One more request: Share the blog article so that more people in the Archaeopark can see on site how people used to live.
A unique, life-size mammoth is another attraction you must have seen.
You support the relatively small town of Niederstotzingen in the very costly task of preserving an extraordinary UNESCO World Heritage Site.
I look forward to welcoming you soon to the Archaeopark.
Your Stefan Merkle
* I generously rounded off the 40 years. It’s only 31 years, but the 40s simply fit the article better.

I can promise you, it’s worth it!
