The free flow of fine bubbles generated by electrolysis and smoke flow in a space enclosed by fire were recently found to show the same tendency thus leading to the introduction of a research technique. The research experimentally models smoke diffusion and flow in parallel and slanted tunnels using the fine hydrogen bubbles generated by electrolysis in a water tank. Visualization laser with wavelength of 532nm and output power of 1000mW is used to visualize effectively the cross section of fine hydrogen bubble flows generated in a model tunnel.
