INTERFACIAL GAS GAP FOR HEAT TRANSFER BETWEEN TWO RANDOMLY ROUGH SURFACES
Abstrakt
This paper describes a statistical method for determining the interaction between two randomly rough surfaces placed face to face. Using this statistical method it is possible to determine the effective gap distance for conduction of heat through the interface gas. A simple method is derived for calculating the standard deviation of a surface roughness from a knowledge of one of the commonly employed surface roughness parameters.
