Для моделирования применена модель VoF (Volume of Fluid), которая позволяет рассчитывать переход жидкости из одной фазы в другую. Следует отметить, что модель VoF способна воспроизводить процессы парообразования исключительно для визуализации, без практического применения численных результатов, что соответствует теоретическим ожиданиям. Актуальность исследования обусловлена глобальным кризисом питьевой воды, что требует повышения эффективности систем опреснения. Данный метод получения чистой воды является одним из наиболее экологически безопасных, что и стало основной причиной выбора объекта исследования. Целью работы является численный анализ и исследование солнечного дистиллятора, сравнительный анализ двух его конфигураций, а также оценка возможных модификаций для повышения эффективности установки. В ходе исследования были смоделированы тепловые потоки внутри установки, а также распределение объемной доли пара и изменение температуры во времени. Полученные результаты демонстрируют более высокую эффективность и производительность двухскатной конфигурации по сравнению с односкатной. Исследование также детализирует физические процессы, происходящие внутри установки, и определяет направления для дальнейшего совершенствования моделирования данной системы в ANSYS.</p></abstract><trans-abstract xml:lang="en"><p>This research presents a comparative analysis of two solar still configurations utilizing the ANSYS 2023R2 software package for computational fluid dynamics (CFD) simulations. The study employs the Volume of Fluid (VoF) model to simulate phase transitions between liquid and vapor, specifically focusing on vaporization processes. It is important to note that the VoF model used in this study primarily serves to visualize vaporization, with its numerical results aligning with theoretical expectations rather than providing practical applications. The relevance of this research is underscored by the global drinking water crisis, which drives the need to enhance the efficiency of desalination systems. Solar distillation is recognized as one of the most environmentally sustainable methods for producing clean water, making it an appropriate focus for this investigation. The primary objective of this work is to conduct a numerical analysis of the solar still, compare the performance of two different configurations, and evaluate potential modifications to improve the system's efficiency. The study simulates heat transfer processes within the distiller, the distribution of vapor volume fractions, and temperature variations over time. The findings indicate that the dual-slope configuration outperforms the single-slope configuration in terms of efficiency and productivity. Additionally, the research provides insights into the physical processes occurring within the distiller and identifies potential areas for further refinement of the system's modeling in ANSYS.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>солнечный дистиллятор</kwd><kwd>двухфазный теплообмен</kwd><kwd>испарение и конденсация</kwd><kwd>ANSYS Fluent</kwd><kwd>численный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>solar still</kwd><kwd>two-phase heat transfer</kwd><kwd>evaporation and condensation</kwd><kwd>ANSYS Fluent</kwd><kwd>numerical analysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Peter H.
