The Flow of a Power Law Fluid in a Melt Fed Single Screw Extruder

A simple numerical method is proposed for the perfect solution is of the two-dimensional power-law circulation equations for a broad channel with a moving boundary. The email address details are used to create a complete style of the isothermal procedure of a single-screw extruder with regard to the compression ratio, the relative lengths of the compression and the metering sections, and the power-law index of the materials. It is shown a true number of the main features of screw extrusion are predicted by the model. By way of examples it is displayed that, in program, the isothermal condition could be relaxed, and satisfactory correlation between the experiment and theory can be acquired, by the use of an average extrusion temp. The model provides a wide theoretical framework, where the relative significance of the geometric parameters and the power-rules index on the throughput-pressure attributes of the screw extrusion can be examined, and the experimental benefits extrapolated and collated. Examples of the solution are presented by means of contour plots to aid designers and users of single-screw pumping machines When you have virtually any concerns concerning where and the way to work with plastic extruder, you possibly can e-mail us on the webpage. .
