Simplified method for calculating thermal conductance of rough, nominally flat surfaces in high vacuum
Year: 1970
Type: article
Abstract: AbstroctA simplified approximate method for calculating the coefficient of thermal contact conductance has been derived.The method applies to the case of rough, nominally flat, outgassed surfaces in contact and under load in a high vacuum environment.The asperities of the surfaces are assumed to be undergoing plastic deformation.The method does not require the use of a computer program, but it does require the use of a surface analyzer and hardness tester.The method is used to calculate the interface conductance of two tungsten cylinders tested at approximately torr and is in good agreement wit1 experimental results.
