The CFD Simulation Analysis Of Garden Plant Configuration And Wind-heat Environment In Shenyang Aineng Nursing Home

With the increasing aging of the population in our country,the outdoor environment design of nursing homes should also receive more attention.At present,most scholars' research on nursing homes is mainly focused on the design of indoor environment homes,ignoring the effects of outdoor environments on physical and mental health for the elderly,and most of them are focused on functionalities and aesthetics in the design of outdoor environments for nursing homes.The lack of attention to the ecological principles and comfort of the environment has often led to the design of green plants not conforming to the actual environment and the behavior patterns of the elderly and often failing to meet the actual needs of the elderly.In this paper,ENVI-met software was used to study the outdoor environment comfort conditions of Shenyang Aineng nursing home in summer and winter under different green plant configuration modes.Through interviews,questionnaire surveys,and behavioral observations of daily activities of elderly people in nursing homes,the main activities of elderly people in nursing homes were determined.Comparing the actual measured nursing home meteorological data with the simulation results of ENVImet software,and verifying that the ENVI-met software simulation method is reliable,solitary planting,opposite planting and linear planting in three types of green of the Shenyang Aineng nursing homes.The outdoor environment comfort in the plant configuration mode was simulated.Research indicates:(1)Compared with the measured data of the Kestrel 5500 hand-held meteorological station at a height of 1.5m,it is found that the simulated value is in good agreement with the measured value,and ENVI-met software is feasible to simulate and analyze the CFD wind-heat environment.(2)In summer solitary planting mode,the best wind environment comfort is the location c deciduous trees plan,the best thermal environment comfort is the location of d deciduous trees plan,the lowest PMV is position d green evergreen trees plan.The best wind-heat environment in opposite planting mode is the deciduous trees plan.The best wind-heat environment in linear planting mode is the deciduous trees + evergreen shrubs.(3)In winter solitary planting mode,the best wind environment comfort is the location of d green trees,the best thermal environment comfort is location b green trees plan,the highest PMV is position b green trees plan.The best wind-heat environment in opposite planting mode is the evergreen trees plan.The best wind-heat environment in the linear planting mode is the evergreen trees + evergreen shrubs plan.(4)The improved plan is effective and feasible for improving the summer and winter wind-heat environment and summer vortex phenomenon in the Aineng nursing home.
