This paper describes the experimental studies on the very slow warm air flow sent off upwards to fiber assemblage from a fine tubing. Schlieren method was employed to make the stream visible.
Results show that when the warm air stream reaches the surface of the fiber assemblage most of it reflects downwards at the surface, some of warm air stream penetrates into the fiber assemblage, and a little portion of it flows out through the fiber assemblage upwards from the upper surface.
These phenomena are analogous to the phenomena observed in electrons which are projected to a solid and show backscattering and penetration in the solid.
