Numerical Simulation Analysis of Model Simplification and Heat Transfer in Position Engineering

In order to determine the processing capacity of the airflow and the air conditioning capacity of the position engineering, the heat transfer process of the air and the wall in the project is analyzed. The actual arch engineering is simplified into equal volume square and spherical engineering respectively. The physical mathematical model of underground heat transfer is proposed, and the initial conditions and boundary conditions are accorded with the engineering practice. The numerical simulation of the heat exchange and related parameters of the airflow and engineering wall is realized by FLUENT software. The paper analyzes and compares the errors of arched structure engineering and two kinds of simplified engineering, and draws the conclusion that it is feasible to simplify the project and simplify the engineering error.
