Thermal Conductivity and Calculation Methods for Spacecraft

Thermal conductivity and thermal issue are inevitable problems in spacecraft and its payload while working.In order to give out the temperature distribution and carry out analysis for temperature effect,the common heat transfer process and actual mathematic model of the heat transfer in spacecraft are introduced.Several numerical methods for thermal analysis and calculation are specialized and thermal network method and finite element method are discussed in detail.The whole system's temperature distribution calculated through these methods offers a reliable basis for spacecraft heat control.
