The reagent filtration flow parameters calculation in gravel dusting during gas-pulse regeneration of wells filters

Abstract

The article proposes a method for calculating the parameters of the filtration flow of the reagent in the gravel dusting of the filter of a water intake well during gas-pulse reagent treatment. To determine the kinematic parameters of the reagent flow that occurs during pulsations of a vapor ‒ gas bubble, a differential equation of the reagent movement in the explosive chamber ‒ gravel dusting-air cap system is obtained. The resulting equation was solved by the Runge‒Kutta method. Taking into account a number of assumptions, an analytical expression was obtained for calculating the maximum speed of the reagent in the blast chamber and gravel dusting.
