Исследования проводились при помощи теоретического анализа, а также численного моделирования теплового движения молекул газа в условиях гравитации свыше 100 000 g. Представлены основные отличия теплопроводности газа в гравитационном поле от теплопроводности газа при отсутствии гравитации. Показано, как тепловое равновесие, обеспечиваемое теплопроводностью газа, зависит от гравитации и разновидности газа. Исследования проводились не только для естественной, но и для искусственной гравитации, создаваемой центрифугой. Выявлено, как тепловое равновесие, обеспечиваемое теплопроводностью газа, зависит от плотности газа в центрифуге. Описаны паразитные эффекты, в том числе теплообмен излучением. Объяснены отличия конвективного теплопереноса при достаточно высокой гравитации от конвективного теплопереноса в условиях земной гравитации. Рассчитаны параметры теплового равновесия, которое обеспечивается конвекцией в газе, находящемся в гравитационном поле. Объяснен механизм горизонтальной конвекции. Предложен способ технической реализации тепловых эффектов, возникающих в газе при гравитации свыше 100 000 g. Даны необходимые технические параметры экспериментального стенда. Детально описана его конструкция.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, using the theoretical and numerical investigation of molecular motion, we study heat transfer processes in the gas placed in a Newtonian gravitational field. The influence of gravity on the heat conductivity of the gas is analyzed. The gravity considered is more than 100 000 times higher than that of the Earth. The main differences of the gas heat conductivity under such high gravity from the one detected under normal gravity are demonstrated and explained. It is shown how the thermal equilibrium for the heat conductivity of the gas depends on gravity and the type of gas. The difference between natural gravity and the centrifugal force is discussed. It is shown how the gas density influences the thermal equilibrium for the heat conductivity under a strong centrifugal force. The convective heat transfer in the gas placed into a gravitational or centrifugal field is analyzed. It is shown that the thermal equilibrium of the convective heat transfer under intensive gravity is not the same as under normal gravity. The horizontal convection mechanism is discussed. A technical way of the realization of gravity thermal effects in the gas is represented. All necessary parameters of the experimental setup are given.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>теплоперенос в газе</kwd><kwd>тепловое движение молекул</kwd><kwd>тепловое равновесие</kwd><kwd>центробежная сила</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heat transfer</kwd><kwd>molecular motion</kwd><kwd>thermal equlibrium</kwd><kwd>centrifugal gravity</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">Olander D.
