Summary

MULTILAYER INSULATION, USING ALTERNATE LAYERS OF SHIELD AND SPACER MATERIAL, IS THE MOST EFFECTIVE INSULATION DEVELOPED SO FAR FOR CRYOGENIC APPLICATIONS. THE EFFECTIVE THERMAL CONDUCTIVITY OF MULTILAYER INSULATION IS A FUNCTION OF VARIOUS PARAMETERS. THE PAPER PRESENTS AN ANALYSIS INVOLVING FABRIC SPACER MATERIAL. THE MODEL CONSIDERS THE HEAT TRANSFER BY VARIOUS MODES SUCH AS SOLID CONDUCTION, CONDUCTION THROUGH CONTACT SURFACES, RADIATION THROUGH THE EXPOSED AREA BETWEEN ADJACENT SHIELDS AND RADIATION THROUGH THE FIBROUS SPACER. GAS CONDUCTION HAS ALSO BEEN CONSIDERED, TAKING INTO ACCOUNT THE ESTIMATED INTERSTITIAL PRESSURE.
