Based on the boundary conditions obtained from the actual measurements during the infrastructure period of Jinghe Dongzhuang Power Station, a calculation model of the predicted bus bar hole environment was established, and a full-scale numerical simulation of the bus bar hole environment was performed based on CFD to analyze the effect of air supply velocity changes on the temperature and velocity fields in the working area. The ventilation effect is evaluated and compared by calculating the inhomogeneity coefficient and air distribution characteristic index. The study shows that an appropriate increase in air velocity can reduce the thermal impact of the internal heat source on the surrounding environment and can effectively control the air quality in the work area. Considered comprehensively, the work area has better comfort when V/V0 is slightly greater than 1. The research results have some guiding significance for the design of bus bar hole air supply system in Jinghe Dongzhuang Power Station.
