| - | * **Pressure profile:** Within this calculation it can be chosen between the polynomial, the linear and a regression calculation model. The linear one bases on an analytical approach based on the theory of single screw extruders. Against this the polynomial calculation and the regression model base on an approximation of numerical results. By selecting the modified option the treatment of the nip region in the calculation can be chosen. From our experience the regression model that was newly implemented in SIGMA 4.5 gives the most reliable results. | ||
| - | * **Melting profile:** Within this calculation it can be chosen between four different models: Compacted, Disperse, Binary and Modified Disperse. The compacted calculation model is a modified Tadmor model as it is known in the theory of single screws. The disperse model presumes that the granulate melts isolated. The binary model takes the melting of binary systems (blends and compounds) into account. The modified dispersed melting model is based on the dispersed model. However, the finite influence duct dimension, the influence of the convection as well as the influence of the particles on the stream will be included additionally within this model. | ||
