    Analysis of dissolution kinetics based on the local isotropic turbulence theory
    (Publishing House of Lviv Polytechnic National University, 2015) Symak, D.; Atamanyuk, V.; Gumnytskyy, Y.
    The dissolution kinetics of potassium sulfate dissolved in water under pneumatic mixing has been investigated. The mass transfer coefficients were determined by the experiments, as well as on the basis of the local isotropic turbulence theory. The ratio between theoretical and experimental data was found to be satisfying that allows to determine the theoretical mass transfer coefficient to calculate the mentioned process. Досліджено кінетику розчинення сульфату калію у воді при пневматичному перемішуванні системи. Визначено коефіцієнти масовіддачі на основі експериментальних досліджень та теоретично на основі теорії локальної ізотропної турбулентності. Показано задовільне співвідношення теоретичних та експериментальних даних, що дає можливість теоретичного визначення коефіцієнта масовіддачі з метою розрахунку даного процесу.
