In order to improve the accuracy and efficiency of numerical simulation of pollutant diffusion law of building decoration materials, a new numerical simulation method of pollutant diffusion law of building decoration materials is proposed. According to the indoor diffusion characteristics of pollutants in building decoration materials, the micro element continuity equation, gas flow rate change rate, energy conservation equation, turbulence energy and diffusion energy consumption equation are calculated to complete the construction of turbulence model. Based on the turbulence model, the pollutant concentration field of building decoration materials and Gauss migration model were calculated, and the migration law calculation results were obtained, and the numerical simulation model was completed. The experimental results show that the numerical simulation results of this model have high simulation accuracy and efficiency in a fixed building environment.
