基于CFD技术对冬季兔舍热环境模拟评估
Simulation Evaluation of Thermal Environment of Rabbit House in Winter Based on CFD Technology
摘要
Abstract
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 environ-ment(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 distrib-uted,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 rela-tive 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.关键词
