An experiment for describing the fluid dynamics in a surfacetension tank under quasizerogravity conditions
Abstract
An experiment is to be automatically carried out on the 19831984 Space Shuttle flight as part of the German MAUS program to study the fluid dynamics in tanks under quasizerogravity conditions. The behavior of the fluid will first be described by analytical and numerical procedures, with the results compared to the experiment. The orientation of the fluid under disturbances will be observed, and procedures for calculating fluid motion in the tank as a result of gravity impulses will be developed. The model tank (a cylinder with a diameter of 100 mm) will be filled with a fluid and laterally and dynamically vibrated; the excitation frequency will be varied from 0.1 to 10 Hz and the excitation amplitude from 0 to 40 mm. The eigenfrequency of the oscillating fluid, the mass size of the oscillating fluid, the damping value corresponding to each mode, and the pressure distribution within the tank will be measured. The construction details and requirements of the various experiment components are given together with block diagrams and schematics.
