| Summary: | 碩士 === 國立海洋大學 === 造船工程學系 === 82 === Considering the design of both industrial tanks and ship tanks,
fluid oscillations in tanks are very important factors to be
considered. In this research numerical studies were made of the
flow of a viscous fluid in three-dimensional rectangular tanks.
Three dimensional Navier-stokes equations and continuity
equation are discretized by using finite difference scheme. The
convective terms were discretized by using upwind difference
and the viscous terms by using centered differences. The fluid
surface is defined by single-valued function and is initially
defined by specifying the surface height above the bottom of
the mesh through the center of each vertical column of cells.
Tanks subjected to different exciting accelerations and
frequencies were studied. Examples of numerical simulation were
compared with the analytical solutions, the results showed good
agreement.
