Modelling the extrusion cooling/calibration stage for complex thermoplastic pro...

The main objective of this work is to implement a 3D non-isothermal multi-domain numerical code, based on finite volume method, able to deal with unstructured meshes that can be used to aid the design of calibration/cooling systems. At the final stage the code should incorporate the major phenomena that take place during profile cooling, including the prediction of the developed thermal residual stresses.

Characterization of the heat transfer coefficient in thermoplastic profile extr...

The main objective of this work is to design a prototype system that will enable the determination of realistic values for h at the interface polymer-calibrator in real and varied extrusion conditions. The data obtained will allow improving the accuracy of the numerical codes that are being developed by the research team, through the implementation of realistic models for h.
