Проведена оценка пожаровзрывобезопасности водорода как топлива, что является актуальным в связи с развитием водородного транспорта. Определены основные причины пожаровзрывоопасности водорода, представлены рекомендации по ее снижению. Установлены отличительные особенности водородных пожаров. Представлены методы и модели расчета газодинамики, тепломассообмена при горении водорода, проведен их анализ. В качестве основной рассматривается модель вычислительной гидродинамики, которая основана на уравнениях неразрывности, состояния, сохранения импульса и энергии для случаев водородных пожаров и взрывов. Обсуждаются исследования струйного горения водорода. Установлено, что хорошее соответствие результатов расчета с экспериментальными данными по основным характеристикам пожар-струи дает вихреразрешающий подход к моделированию турбулентности. Дальнейшее развитие моделей горения водорода связано с проведением расчета поверхности потенциальной энергии частиц.

The article evaluates the fire and explosion safety of hydrogen as a fuel, which is relevant in connection with the development of hydrogen transport. The main causes of the fire and explosion hazard of hydrogen are identified, and recommendations for its reduction are presented. The distinctive features of hydrogen fires have been established. Methods and models for calculating gas dynamics and heat and mass transfer during hydrogen combustion are presented, and their analysis is carried out. The main model of computational fluid dynamics is considered, which is based on the equations of continuity, state, conservation of momentum and energy for cases of hydrogen fires and explosions. Studies of jet burning of hydrogen are discussed. It is established that a good correspondence of the calculation results with experimental data on the main characteristics of the fire jet provides a vortex-resolving approach to turbulence modeling. The further development of hydrogen combustion models is related to the calculation of the surface potential energy of particles.
