| Popis: | We present theoretical and experimental results on the study of forces acting on cells in suspensions in the field of a standing ultrasonic wave (by the example of rat and guinea-pig erythrocytes, yeast, and chlorella) and leading to cell and liquid phase exfoliation, cell separation into fractions, and cell concentration in variable-pressure nodes. The experimental results are presented as plots in the coordinates of the average density of the energy of the ultrasonic field and the linear velocity of the flow of the cell suspension. Straight lines in the plots separate the regions of cell concentration, separation, and washout. The slope of these straight lines is a characteristic of a certain cell type. Agreement of the experimental and theoretically predicted data is shown. |
