Analysis of fluid motion during jigging

Flow of water inside a jig has a strong bearing on the rate of stratificati on of particles, For this reason, various fluid waveforms are proposed for achieving optimal stratification rate. In the present investigation, the fl ow of water is analyzed in a carefully controlled laboratory jig. In a very simplified manner, the amplitude and frequency of pulsation is controlled by means of the compensator pressure and a level sensor. This allows for pr oper analysis of the dynamics of motion of the fluid as function of the amp litude and frequency of pulsation. Furthermore, the effects of amplitude an d frequency of pulsation on the stratification behavior of the particles is analyzed to establish the existence of an optimal operating condition in t erms of amplitude and frequency of pulsation.
