物料悬浮速度测试方法研究

悬浮速度是物料空气动力学的一个重要参数,一直是从事物料特性研究者关心的问题。但是国内外对物料悬浮速度测试的研究一直很少,主要以简单的机械机构控制和理论计算测试为主,存在着操作繁琐、计算复杂、数据误差大等缺点。为此,重点对比分析了几种物料悬浮速度测试方法的测试原理与特点,旨在为相关研究提供参考。

Research on Methods of Grain Suspension Velocity Test

The supension velocity is a very essential parameter of aerodynamics which is concerned by who pursue the research of grain's characteristic all the time.But there is few research about test apparatus except the simple mechanism and theoretical computing with the defects of complicated operation and great errors all over the world.This paper mainly compares and analyzes the mechanism and characteristic of grain supsension velocity test methods.
