基于正交试验和Fluent仿真的作物残茬防风蚀效应研究

Study on Protection Wind Erosion Effect on the Erect Stubble of Crops Based on Orthogonal Design and Fluent

利用可移动式风蚀风洞进行了作物留茬地表抗风蚀试验,对不同作物种类、留茬高度、覆盖度的留茬地表防治农田土壤风蚀的保护能力进行研究,应用正交设计来安排试验。利用计算流体力学(CFD)软件Fluent对0FDY-1.2型可移动式风蚀风洞中气流流场进行模拟,直观地了解作物留茬对风洞内流场的影响。

The trial utilizes of movable wind tunnel tests for different types of crops,stubble height,overlay degree of the field,and study the protection ability of the stubble band,and study the application of orthogonal design to arrange tests.The paper used Fluent,a software of computational fluid dynamics,to simulate the 0FDY-1.2 movable wind-tunnel indoor test in numerical simulation of air flow.Intuitive understanding of crop stubble on the wind tunnel flow field.
