摘　　要：采用数值模拟技术对集聚区进行模拟仿真,可以形象、直观地对气流分布做出分析和评价。为此,采用Fluent数值仿真法,模拟了核桃去空壳机的风道气流分布变化。结果表明:数值模拟内流场分布规律与试验测得的结果基本相符,证明了使用数值模拟来研究风道内流场的方法是有效可行的。本章将流场仿真技术引入筛选风道,为高效、快捷地开发筛选机械提供了一种新的思路和方法。Numerical simulation techniques for gathering areas of simulation, you can image, intuitively make air distribution analysis and e- valuation. For this reason, the use of fluent numerical simulation method to simulate the walnut shell machine air distribution duct changes. The results show that： the law of the flow field and test results measured by the numerical simulation of the basic line, proved to study the flow field in the wind tunnel using numerical simulation method is feasible and effective. This chapter will introduce the flow field simulation technology screening duct, as efficiently and quickly develop a screening machinery to provide new ideas and methods.
