The Coupling Analysis and Research of Temperature and flow Field

Abstract

To the solid rocket axisymmetric thrust‐vectoring nozzle, under the action of flow field and temperature field, Comsol Multiphysics is used for this mechanism to simulate the load deformation and thermal deformation of the convergent plate, sheet, rod expansion regulation and other components, and to analyze the dynamic characteristics of the system in the generator mode under the two field coupling. Simulation and analysis to forecast the deformation of the mechanism accurately have important theoretical significances to the design of the system.
