Calibration of Numerical and Determination of Physical Parameters for the Organic Model System TRIS-NPG
Abstract
Studies on the formation of layered peritectic solidification structures have been carried out by using the model system TRIS-NPG (tris[hydroxymethyl]aminomethane - neopentylglycol). As such structures are highly affected by thermo-solutal convection, further studies are planned aboard the International Space Station in 2020/21. Since convection is always present on earth, the required process conditions for µg-experiments need to be elaborated by experiments under earth gravity (1g) conditions, also by numerical investigations. In order to do so, not only adequate physical properties are required, but also numerical parameters have to be characterized. Given that there is an insufficient knowledge of corresponding physical properties for the model system, the determination of the required parameters takes place by parameter variation with the aim to match with the obtained experimental results.
