METHOD AND APPARATUS FOR DETERMINATION OF SEDIMENTATION STABILITY ANDSEDIMENTATION ANISOTROPY ANGLE

A new method of the absorption type is suggested for the determination of the gravitational sedimentation stability and sedimentation anisot ropy angle of the liquid polydisperse systems. The average intensity o f the radiation (in particular, laser radiation), which is transmitted in two directions of the medium studied: along (or opposite) and tran sversely with respect to the intensity of the uniform gravitational fi eld, is measured at each unit time of the sedimentation. A new complex physical value, sedimentation anisotropy of the liquid polydisperse s ystems, is introduced. Its module and argument characterize the sedime ntation process. This value serve as a more complete qualitative descr iption of the liquid polydisperse systems. The apparatuses for this me thod are suggested.
