Construction and application analysis of ventilation model for grain storage
摘要
Abstract
The temperature and moisture content of wheat in the safe storage process is two very important factors,and the simulation of the grain filling process can realize the real-time and effective monitoring of the grain moisture content in the process of grain storage ventilation,and ensure the safety of grain storage.The paper,based on the heat and mass transfer in the porous medium theory,established the model of grain interior ventilation,and by using Fortran programming to numerical simulation the internal heat coupled moisture transfer process and the variation of temperature and water of ventilation in the grain silo,made a test in Changle County of Shandong Province during grain storage ventilation for 6 days.Through the comparison of simulation results and measured data,the results show:the change trend of temperature and moisture content is consistent with the measured value of model prediction,the maximum difference of moisture content of grain is 0.93％,the maximum temperature difference is 2.1 ℃,deviations are within acceptable limits;in the same condition,the ventilation model,Fortran programming simulation time is only 0.256 s,the model with short time,convenient operation;through the process of adjusting the physical parameters,the model can also be applied to other complex biological characteristics of the material storage,and it is beneficial to create a safety storage environment and reduce the loss in storage.关键词
