 <abstract xml:lang="en">
 <p>This study investigated the efficiency of mass transfer within a two-phase absorption reactor. Mass transfer within the reactor was investigated using numerical simulations in Ansys Fluent. The numerical simulations yielded velocity, pressure, and phase volume fraction fields, as well as the wetted surface area of the bed. These results enabled the selection of a reactor layout with improved contact between the liquid and gas phases.</p>

 <trans-abstract xml:lang="ru">
 <p>В работе исследовалась эффективность массообмена внутри двухфазного абсорбционного реактора. Массообмен внутри реактора исследовался путем численного моделирования в программе Ansys Fluent. В результате численного моделирования получены поля скоростей, давления и объемной доли фаз, а также определена площадь смоченной поверхности слоя. Полученные результаты позволили подобрать компоновку реактора с улучшенным контактом между жидкой и газовой фазами.</p>
