how the gaming console fan(s) collect dust while their are spinning rapidly all the time?
In: Technology
Boundary layers. Air is slightly viscous, and this means if air is blowing over a surface, or if a surface is moving through the air, there is a very very thin region right at the surface where the air is “stuck,” and the windspeed is almost zero. If a speck of dust is smaller than this layer, then there isn’t enough airflow to push it off
