摘　　要：本研究基于计算流体力学(CFD)模拟技术对兔舍热环境(风速和温湿度)进行三维稳定状态的模拟分析,旨在评估密闭兔舍冬季热环境质量。结果表明:密闭兔舍环境的调控采用低效率排风系统,中间区域存在气流流动死角,风速分布不均,不符合兔舍最适宜的风速范围;温度从西侧的进风口到东侧的出风口呈上升趋势,分布范围为15.56~22.40℃,符合兔舍最适宜温度范围;相对湿度的分布变化与温度则呈相反趋势,分布范围为54.39%~81.78%,略超出兔舍最适宜相对湿度范围。温度和相对湿度的实测值与模拟值的相对误差范围均低于5%,说明运用该模型评估环境因子是可行的。本研究为优化商品兔舍冬季环境的调控方案提供了参考依据。The objective of this study was to evaluate the thermal environment quality of closed rabbit houses during winter through a three-dimensional stable state simulation analysis of the thermal environment(wind speed,temperature,and humidity)in the rabbit house based on computational fluid dynamics(CFD)simulation technology.The results showed that the closed rabbit house environment was controlled by a low-efficient exhaust system,with a dead angle of airflow in the middle area.The wind speed was unevenly distributed,which did not meet the favorable wind speed range of the rabbit house.The temperature showed an upward trend from the air inlet on the west side to the air outlet on the east side,ranging from 15.56℃to 22.40℃,which was in line with the most suitable temperature range of the rabbit house.However,the distribution of relative humidity showed an opposite trend to temperature variation,from 54.39%to 81.78%,which was slightly beyond the optimum relative humidity range of the rabbit house.The relative error range between the measured and simulated values of temperature and relative humidity was less than 5%,indicating that it is feasible to use this model to evaluate environmental factors.This study provides a reference for optimizing the regulation scheme of the commercial rabbit house in winter.
