Savik V. Improving of efficiency of foamgenerating devices in pump circulation systems of rigs

The abstact is devoted to problems of effective improving of foamgenerating devices in pump-circulation systems rigs. Having made the research we have verified theoretically and confirmed experimentally the actuality and the efficiency of foamcreating in the developed foamgenerating ejection device with the ability to change its basic geometrical parameters for the desired mode of operation by changing the internal structural elements. We have described mathematically the motion of gas-liquid mixture in foamgenerating ejection device from the nozzle insert to the place of shock wave, where it is transformed in liquid-bubble mixture (foam). We have done the computer modeling of fluid flows, air and their mixture during the motion in the developed device. We have suggested the mathematical model, which has helped us define the basic parameters of fluid flows, air and their mixture during which there could be achieved the maximum efficiency in process of foaming. Basing on experimental and industrial research and testing, we have defined the parameters of foamgenerating device for the most effective process of foaming and made the recommendation for its usage in industrial environments.
