Abstract:Focusing on the effect of granularity measuring result by random motion in the area of ream small particles,a model of particles in flow field is presented according to the theory of dynamics.Then,systematic study is made about the orientation characters of particle in different entrance angles and flow field of different characters with the aid of numerical computation.Finally,conclusion is drawn about the relationship among time,size character of the particle and the flow field,which makes the accurate(measurement) of the particle granularity possible.particle;size;granularity;orientation;flow field
