摘要

The use of the singularity method for the calculation of fluid vibrations under reduced gravity, due to surface tension effects was investigated, starting from the basic flow equations of an incompressible, inviscid fluid. Examples show that problems with a Liapunov boundary plane can be very well solved numerically, as well as problems with a stuck-edge boundary behavior in the corners. Free-edge problems require solutions especially adapted to the geometry. The method is less suited for the calculation of fuel motions in satellite tanks, but useful for the study of the dynamic behavior of nonrotating fluid configurations.
