For producing a point source of smoke in a wind tunnel environment, Concept have the Aerotech smoke system, with a heated tip on the end of a thin wand.
For seeding a wind tunnel for LDA/PVA type work the ViCount 1300 system is normally supplied. This can produce either water or oil based smoke with minor re-programming, so it is a very adaptable solution.
The ViCount is such a versatile machine, that it's capable of everything from seeding the world’s largest wind tunnel (NASA AMES) through to producing fine smoke rakes in educational wind tunnels.

The speed at which the unit builds smoke is very impressive and consistently in line with the guidance given by yourselves.
The nature and density of the smoke produced proves very effective when observed from outside the building giving sufficient time for and allowing easy observation of emerging smoke and leakage paths. The very persistent effect has allowed us to test buildings with volumes up to 40,000 m3 with just two units.
The very dry nature of smoke (i.e. small particle size) has meant that there have been no instances of contamination of the buildings following the test.
We have found the continuing technical support provided by Concept to be prompt and effective in answering queries and allowing us to get the most out of our equipment."
