 The internal temperature control is calculated iteratively. \\ The internal temperature control is calculated iteratively. \\
-First, the temperature curve without internal temperature control is always calculated. The steady-state heat flows for the constant screw base temperature profile can be calculated from the known volume flow of the temperature control medium, the geometry and thermal conductivity of the screw and the inner tube as well as the known screw base temperature. \\ +First, the temperature profile without internal temperature control is always calculated.

-The temperature calculation is then carried out again, taking into account the heat flow into the tempered screw core. The resulting temperature reduction only occurs at the base of the screw and leads to an inhomogeneous temperature profile over the channel height. As a result, a cooler screw base temperature is calculated, which in turn is used to calculate the heat flows in the tempering medium and within the screw. \\+The temperature calculation is then carried out again, taking into account the heat flow into the tempered screw core.

 With the heat flow into the screw core now reduced, the temperature calculation is started again. The process is carried out iteratively until a stationary process is reached. With the heat flow into the screw core now reduced, the temperature calculation is started again.
