AIR FLOW VISUALIZATION BY HELIUM BUBBLE TRACING TECHNIQUE

Graphical Abstract

Abstract

Abstract

Some typical aerodynamic flow patterns that related to industrial furnaces have been successfully photographed by using the helium bubble tracing technique.
The apparatus and the bubble solution are made in the laboratory of BUIST.
By using a multi-exposure method more stream lines were catched in the focus, it is especially useful for studying the air flow pattern mainly affected by the jet from a coal water slurry burner, or a RK type oil burner.
