dc.description.abstract | The first part of diploma thesis shows research in polymer melt flow in Extruder. In the next part Velocity and pressure drop from obtained data from the literature is found. With volumetric flow and pressure drop is obtained. Next part of diploma thesis is CFD analysis and its results are compared with data from analytical solution In the penultimate part, are investigating the CFD analysis changes in the pressure drop, depending on the model and boundary conditions diploma thesis deals with polymer melt flow in extruder screw. It is important to know the velocity field in the cavity of the screw when the screw design for melt transportation is performed. The melt has to be homogenized also considering heat transfer into the mass from the heated screw cylinder. Create the model of melt flow in the screw of the extruder for given geometric parameters of a screw, physical parameters of melt and operation conditions of the process. The screw revolution is constant, and the model will not include heat transfer. The results of the thesis will be the determination of the velocity field in the cavity of a screw and approximately comparison of pressure loss with calculation or values from the literature | cze |
