摘 要：Because the mechanism of thermal contact resistance is complex,it is entirely neglected in thermal structure analysis of composite *** research object is a typical composite nozzle which has two layered divergence *** adhesive is carbonized when the temperature exceeds 200℃and the interface on two layered divergence cone is full of macromolecule ***,thermal contact resistance should be *** on Galerkin theory,the thermodynamic finite formulations of axisymmetrical thermal contact resistance element are *** value of thermal contact resistance is estimated through experimental data by home code for transient heat *** results show that thermal contact resistance has strong influence on heat transfer of two layered divergence *** from the heat transfer,two layered divergence cone structure have an adiabatic effect on outer *** thermal structure analysis,the calculated temperature on nozzle wall compares favorably with experimental data when the numerical value of thermal contact resistance is approximate 0.025m·℃/*** reverse method of thermal contact resistance provides reference for precise heat transfer on composite nozzle.
