The same processes occur in regular polyhedrons. We can calculate the maximum heat transfer rate, the so-called critical heat transfer rate. We must assume here identical conditions of heat exchange on all internal and external walls of a regular polyhedron. The transfer rate of heat penetrating through the regular polyhedron with different heat transfer coefficients on the walls is called the heat transfer rate with asymmetric boundary conditions. We show that the heat transfer rate in this case will grow up if we replace those coefficients with their average values.}, type={Artykuły / Articles}, title={Heat transfer through the regular polyhedrons with asymmetric boundary conditions}, URL={http://journals.pan.pl/Content/94362/PDF/10_paper.pdf}, doi={10.2478/v10173-012-0023-y}, keywords={Heat transfer rate, Regular polyhedrons, Asymmetric boundary condition}, }
