   <abstract xml:lang="ru">
    <p>Проанализированы проблемы охлаждения крыши резервуаров вертикальных стальных. Поставлена задача комплексного влияния режима движения охлаждающей жидкости, расстояния от среза пожарного ствола до охлаждаемой плоскости и  продолжительности процесса в точке торможения нестационарной осесимметричной импактной струи. Получено аналитическое решение уравнения энергии, оформленное в виде критериального уравнения. Установлено, что при существенных расстояниях между срезом сопла пожарного ствола, когда Fr &lt;&lt; 1, интенсивность теплообмена между свободно падающей импактной струей огнетушащего вещества становится более значительной. Установлено, что при  Fr &gt;&gt; 1 интенсивность теплообмена не зависит от величины этого расстояния, а в иных случаях она возрастает. Констатировано, что для диспергированной структуры струи усредненные характеристики теплообмена существенно увеличиваются для малой продолжительности импульса.</p>

    <p>Analysis of problems of cooling a roof of vertical steel tanks. The problem of the complex effect of the coolant flow mode, the distance from the cutoff of the fire barrel to the cooled plane, and the duration of the process at the braking point of an unsteady axisymmetric impact jet is posed. An analytical solution of the energy equation is obtained, formulated as a criterion equation. It is established that at significant distances between the nozzle section of the fire barrel, when Fr &lt; 1, the intensity of heat exchange between a freely falling impact jet of extinguishing agent becomes more significant. It is established that at Fr &gt; 1, the intensity of heat exchange does not depend on the magnitude of this distance, and in other cases it increases. It is stated that for a dispersed jet structure, the average heat transfer characteristics increase significantly for a short pulse duration.</p>
