Numerical Simulation of Gas Pipe with High Temperature and High Pressure

Abstract:

Aiming to characteristics of structure and transmitting medium of gas pipe with high temperature and high pressure, considering the coupling effect of static pressure and temperature, the thermal structure coupling model based on steady-state heat conduction is established according to the finite element theory. So method and process of numerical simulation on thermal structure coupling analysis are proposed. Simulation analysis is carried out for the gas pipe of a dry-gas compressor. The variation characteristic of inner-outer wall is revealed under the different temperature. The results indicate that the numerical modeling and simulation of thermal structure coupling of gas pipe with high temperature and high pressure can be realized. It can provide valuable reference opinions for site construction, real-time monitoring and safety analysis of pipe.
