基于MATLAB的文丘里模型和普通模型下鸡舍流感病毒的数字模拟和仿真

Digital Simulation and Simulation of Influenza Virus in Henhouse Based on Venturi Model and General Model Based on MATLAB

为有效解决当前鸡舍中禽流感等病毒和粉尘的传播问题,设计了一种新型的鸡舍笼架摆放模型,提出了一种以文丘里模型为基础的鸡舍模型。根据相关数学和统计学原理,建立流感病毒的数学模型,并利用MATLAB软件对新型文丘里鸡舍和普通鸡舍分层分向对病毒模型验证比较;利用Fluent软件对新型文丘里鸡舍模型进行分层风力场、温度场模拟仿真,结果表明,普通模型在感染病毒后鸡只全部死亡,新型文丘里模型在高约1.5 m处,鸡群成活率较高大约55%左右,其余高度处鸡群仍有存活。该模型能更好地改善和抑制病毒的传播,其风力场和温度场的分布有更好的规律性和可控性,在进行与普通的鸡舍笼架摆放相比,新型文丘里模型在风力场、温度场和病毒传播路径方面有更好的可控性和适用性。

In order to effectively solve the problem of the spread of avian influenza virus and dust in the henhouse,a new kind of bird cage model is designed,and a hen model based on the Venturi model is put forward. According to the relevant mathematical and statistical principle,mathematical model of the influenza virus,and the new Venturi sheds and ordinary sheds hierarchical to virus model validation and compared by MATLAB software;using Fluent software on the new Venturi model sheds stratified position,wind temperature field simulation results show that the general model in infected chickens all the death of Venturi,the new model in the high of about1. 5 m,the chickens have higher survival rate of approximately 55%,remaining at the height of chickens is still alive. The model can better improve and inhibit the spread of the virus,the position of wind and temperature field distribution has better regularity and controllability,compared with ordinary chicken in the cage placed,new Venturi model has better controllability and adaptability in the wind position,temperature field and virus transmission path.
