ABSTRACT

The problems of inclusion of the thermal resistance in metal surfaces contact which are caused by discrete character of resistance take a special place in practice the thermal calculations of power plants. Nowadays the most familiar calculations models are appropriate for gaining in-formation on forming of a contact resistance (CTR) for special cases of thermal contacts. Therefore, the synthesis of the available experimental data, taking into account the main factors determining the formation of the CTR has a certain practical interest.

KEYWORDS

contact thermal resistance, dependence.

Аннотация: Большое значение в практике тепловых расчетов энергетических установок занимают проблемы учета термических сопротивлений контактов металлических поверхностей, обусловленных дискретным характером соприкосновения. Имеющиеся в настоящее время расчетные модели пригодны для получения информации о формировании контактных термосопротивлений (КТС) для частных случаев тепловых контактов. Поэтому, определенный практический интерес представляет обобщение имеющихся опытных данных с учетом основных факторов, определяющих формирование КТС.
