Duct Cleaning Brush
- Ducts are used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. These needed airflows include, for example, supply air, return air, and exhaust air. Ducts also deliver, most commonly as part of the supply air, ventilation air.
- An implement with a handle, consisting of bristles, hair, or wire set into a block, used for cleaning or scrubbing, applying a liquid or powder to a surface, arranging the hair, or other purposes
- an implement that has hairs or bristles firmly set into a handle
- a dense growth of bushes
- A thin stick set with long wire bristles, used to make a soft hissing sound on drums or cymbals
- An act of sweeping, applying, or arranging with such an implement or with one's hand

A simple model of a rotating duct cleaning brush was presented using large deformation elastic theory. The results obtained with the model were compared with the results obtained by a laboratory test. In particular, the effect of air drag on the behaviour of the brush was considered. The results show that with normal brush properties, air drag increases the torque needed and reduces somewhat the contact force between a bristle tip and the duct surface. However, air drag has only a slight effect on the deflections of the bristles at the practical rotating speeds of the brush (300-1000rpm) in a round duct. The modelled and experimental results for the torque caused by air drag were in good agreement in the case where the brush rotated without contact and when a reduced air speed coefficient of 0.5 was used in the simulation. The developed model can be used as a first step in the systematic design of rotating brushes. However, further research is needed to determine the relationship between bristle tip contact and cleaning efficiency.

This is real, this is how it is, no kidding.
I flit about from one technique to another so rapidly when crafting that I have always got bits and pieces around. My work space actually is a camping table in the loft. The white board in the center foreground is always on my kness because there is no table surface free.
