Тепломассоперенос в капиллярно - пористых покрытиях протекал с избытком жидкости за счет совместного действия капиллярных и массовых сил. Описана динамика паровых пузырей и их термогидравлические характеристики, наблюдаемые оптическими методами исследования. Разработана физическая модель процесса тепломассопереноса в реальной пористой структуре. Для такой модели решена задача термоупругости и определено предельное состояние системы хорошо - и плохотеплопроводных материалов (пористое покрытие на металлической подложке). Определены тепловые потоки, подводимые к поверхности, время их воздействия на создание разрушающих напряжений, размеры отрывающихся частиц и глубины проникновения температурной волны в подложку. Тепловые потоки подсчитывались от времени взрывообразного появления первого зародыша (10-8 с) до времени разрушения материалов (102 - 103 с), т.е. от времени релаксации до времени, описывающего микропроцесс. С увеличением величины q в нагреваемом слое и, следовательно, уменьшением времени нагрева τ, растет роль напряжения сжатия. Несмотря на высокую сопротивляемость сжатию, разрушение от сжимающих термонапряжений происходит в более благоприятных условиях мгновенного и в малых объѐмах. Теория подтверждена экспериментом, полученным в результате наблюдения камерой СКС-1М. Разрушение капиллярно-пористых покрытий происходит в результате потери устойчивости в тонком слое, прилежащим к свободной поверхности. Поэтому рассматривалось напряженное состояние верхнего слоя, толщина которого зависит от коэффициента теплоотдачи, структуры покрытия и подложки (металлической парогенерирующей поверхности).</p></abstract><trans-abstract xml:lang="en"><p>Modeling of the low heat conductive low-porous capillary porous coatings and metal (copper, stainless steel) surfaces (base layer) was studied. Heat and mass transfer in the porous coatings moved with excessive liquid due to the combined action of capillary and mass forces. The dynamics of vapor bubble was described along with their heat-dynamic properties, which were observed by the optic research methods. Finding solution for the thermoelasticity allowed to reveal the influence of the specific heat flow and heat tension of compression and stretching depending on time of supply and sizes of pulled particles at the time of the system limit state as to "porous coating - base layer". The theory was confirmed by the trial, which was observed by camcorder SKS-1М.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>капиллярно-пористые покрытия</kwd><kwd>естественные минеральные среды</kwd><kwd>термоупругость</kwd><kwd>напряжения сжатия</kwd><kwd>напряжения растяжения</kwd><kwd>модель</kwd><kwd>элементы энергоустановок</kwd><kwd>тепломассообмен</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">Genbach A.A., Bondartsev D.Yu., Iliev I.K.
