Fluid handling in spacecraft

This lecture treats the behavior of liquids under conditions in which spacecraft operate. These conditions are mainly variable accelerations up to the compensation of gravity, which leads to the dominance of capillary forces. Several techniques to manage the liquid with respect to the requirements from the spacecraft operators are presented.

Lernergebnisse

• Understanding the connection between accelerations of a spacecraft and liquid behavior
• Connection between thrust, acceleration, and propellant demand
• Understanding fluid mechanics on tank scale, component scale, and subcomponent scale
• Design tools for two-dimensional situations
• Design equations for propellant management devices
