Finite Element Analysis of Reaction Vessel for Measuring the Solubility of Supercritical Carbon Dioxide
The thermal-structural coupling analysis of the pressure vessel arecarried out by the finite element method to verify its safety, and the stress section are linearized. The results show that the analysis value of the temperature value of the vessel cavity are basically consistent with the change trend of the measured value, and the steady state error are only 2.7%; there is a large stress concentration at the opening of the upper window, and the maximum coupled stress value of the internal surface is 176.2 MPa. The maximum stress path is evaluated based on the analytical design standard JB4732-1995, and the structure satisfies the strength requirement.
