Zusätzlich zu den genannten regelun

Zusätzlich zu den genannten regelungstechnischen Maßnahmen wurden während der Versuche im Überdruckbereich weitere Maßnahmen zur Minimierung des signifikanten Einflusses der Konvektion im Druckbehälterinnenraum auf die Messergebnisse notwendig. Es war geplant, durch eine Änderung des axialen Temperaturfeldes eine Verringerung der treibenden Kraft für eine Strömung innerhalb des Druckbehälters zu erreichen. Diese Maßnahme blieb jedoch ohne Erfolg, sodass sich weitere konstruktive Maßnahmen als erforderlich erwiesen. Zu diesem Zweck wurde die Plattenanordnung innerhalb der Messapparatur von Schüttungen, Faserdämmstoff sowie einem Metallzylinder umhüllt. Der Einfluss der Konvektion auf die Plattenanordnung konnte so weitestgehend minimiert werden. Die noch verbliebene Konvektion zwischen dem Metallzylinder und den Heizzonen führt zu einem erhöhten Kühlbedarf in der oberen Haube.

In addition to these regulatory measures further measures were necessary during the trials in the pressure area to minimize the significant influence of convection pressure inside the tank on the measurement results. It was planned to achieve a reduction of the driving force for a flow within the pressure vessel by a change of the axial temperature field. This measure remained but without success, so that proved to be more constructive measures as required. For this purpose, the plate arrangement within the measuring equipment of pours, fiber insulation, as well as a metal cylinder was wrapped. The effect of convection on the plate arrangement could be minimized so as far as possible. The remaining convection between the metal cylinder and the heating zones leads to an increased cooling demand in the upper canopy.

In addition to these technical control measures additional measures to minimize the significant influence of convection in the pressure vessel interior to the measurement results were necessary during the tests in the overpressure range. It was planned to be achieved by a change in the axial temperature field reducing the driving force for flow inside the pressure vessel. This measure, however, remained without success, so that more constructive measures proved necessary. To this end, the panel assembly was encased within the measuring apparatus of lifting devices, fiber insulation and a metal cylinder. The influence of convection on the panel assembly could be largely minimized. The still remaining convection between the metal cylinder and the heating zones leads to an increased cooling requirement in the upper hood.

in addition to the above-mentioned control measures during experiments in überdruckbereich further measures to minimize the significant influence of convection in the druckbehälterinnenraum on the results of the measurements are necessary. it was planned by changing the axial temperaturfeldes reduce the driving force for a flow within the vessel to reach. this measure, however, without success, so that further constructive measures as necessary. for this purpose, the plattenanordnung within the measuring apparatus of pile, faserdämmstoff and a metal cylinder surrounds. the influence of convection on the plattenanordnung could be minimised as far as possible. the remaining convection between the metal cylinder and the heating zones leads to an increased cooling requirements in the upper canopy.
