基于 CFD 数值模拟方法的日光温室建模研究
Modeling Research on Greenhouse by Solar Heat Based on CFD Numerical Simulation Method
摘要
Abstract
With the development of computer software technology , CFD numerical simulation of fluid simulation has been more widely applied in practical engineering but less in agriculture .CFD can form the numerical modeling of the size and shape of real environment , it can simulate temperature , pressure and velocity field parameters of the real environment . We can compare the results of two-dimensional simulation with that of three-dimensional simulation .By using CFD nu-merical simulation technology , taking the environment for the growth of greenhouse as an example , the greenhouse venti-lation , temperature and humidity were investigated by numerical simulation , the calculation showed that the maximum temperature of greenhouse ventilation reduced from 307K to 304k,which has changed significantly to verify the accuracy of the numerical simulation .Based on the numerical simulation of CFD , humidity , ventilation is good after gas liquidity without agglomeration of hot air , which is very conducive to the growth of crops and provides the theory reference for the crop growth environment of solar greenhouse .关键词
