Imitation design of process motions of foam at the subsurface extinguishing
On the basis of the worked out mathematical model of motion of foam at the subsurface extinguishing of fire in tanks with an oil product the imitation design of process is produced taking into account objectively existent variation of parameters of extinguishing and influence of external factors. A criterion is time of extinguishing that is determine adding up of values of time on three stages : time of motion of foam on a technological pipeline, time of getting up of the first portion of foam to the conflagrant surface, time of spreading of foam on the surface of oil product to the walls of reservoir. The most probable values of criterion, that can be used for prognostication of time of extinguishing, are certain.
