An Approach to Determine Thermal Properties of Spaceborne Solid Materials

Autor: Furkan Kulak, Deger Akin, Dilek Kumlutaş

Thermal conductance of contacting surfaces is an important parameter for spacecraft thermal design. No universal model exists that can enable one to predict contact resistance between any two surfaces. If none of the available models fit the need for
