Özet:

 

In this study, sloshing inside partially filled enclosed  baffled and unbaffled tanks was investigated.  The fluid is assumed to  be homogeneous, isotropic, viscous, and Newtonian and exhibiting only  limited compressibility.  Tank and fluid motions are assumed to be  two-dimensional.  A moving coordinate system is employed so that the  tank movement is set to rest.  The volume of fluid technique will,  then, be used to track the free surface.  The model solves the  complete Navier-Stokes equations in primitive variables by the use of  finite difference approximations.  At each time step, a donor-acceptor  method is used to transport the volume of fluid function and hence the  locations of the free surface.  Ten different cases including baffled  and unbaffled tanks with different fill depths are studied near and on  the resonant frequency.  In order to assess the accuracy of the method  used, computations are compared with theoretical and experimental  results.
