INTERACTION BETWEEN AIR-FILLED FOAM JETS OF DIFFERENT EXPANSION RATIOS: EXPERIMENTAL STUDY
Using of low expansion foam for transportation of medium expansion foam was experimentally checked. The results showed that the throwing range of the combined jet is more than 18 m. The influence of the supply pressure of the water-foam mixture for the formation of air-filled foam of optimum multiplicity in foam generators was also investigated. The effect of synergism during the extingushing fires of flammable and combustible liquids was revealed. This effect was observed after interaction between burning-surface area and combined foam. The average expansion value of the combined foam was calculated (the value was more than 54).
