EFFECT OF VIBRATION SHEAR ON POLYSTYRENE CELL MORPHOLOGY

摘要

A novel microcellular processing experimental setup is developed. With this setup, an oscillatory shear flow is superimposed perpendicular to a steady shear flow during microcellualr processing. The effects of processing condition such as processing pressure, shear rate and vibration frequency on polystyrene cell morphology are investigated. The results show that the cell density increase and cell size decreases with the increase of processing pressure, shear rate and vibration frequency.
