Measure and Analyze of the Bubble Movement in Polymer Melt Flow Field
In recent years much research work has been reported about the bubble deformation and dispersion under the multiphase polymer melts flow field. This investigation has a great significance upon the bubble deformation or mixing of the multiphase polymer blends .Similar to this,the movement of bubble and the shape of bubble under polymer melts flow field is also well worth studying since its importance upon the dispersion and mixing of the two phase polymer blends. To obtain the rules of movement of bubble under the polymer melt flow field ,a series of experiments were carry out observations the gas bubble movement track under the polymer melts flow field using the direct visual flow-field, through changing the experiments condition such as temperature, gas injection pressures and so on. It was found that the track of gas bubble for the different experiments condition were changed greatly, track of bubble was severely affected by the velocity of the polymer melts. Therefore several different track of bubble were characterized.
