自然通风条件下多塑料大棚群温度场的CFD分析
CFD Analysis of Temperature Distribution for Multi Naturally Ventilated Plastic Greenhouses
摘要
Abstract
In order to research the temperature distribution in multi plastic pipe greenhouses, the standard k-εturbulent model and DO radiation model were used for homologous numerical model.The measurement was conducted to validate the numerical model and CFD analysis was done for temperature distribution under natural ventilation.The results showed the simulated values and measured values matched well, the average relative error was 4.2%.Then the numerical model was used to predict the temperature distribution for different distances between greenhouses, the results showed increasing the distance between greenhouses could reduce the average temperature in the leeward greenhouse and increase homoge -neity.The difference in average temperature among greenhouses cloud also decrease.关键词
