Computer modeling of the dynamics of surface tension on rotating fluids in low and microgravity environments
Abstract
Timedependent evolutions of the profile of the free surface (bubble shapes) for a cylindrical container partially filled with a Newtonian fluid of constant density, rotating about its axis of symmetry, have been studied. Numerical computations have been carried out with the following situations: (1) linear functions of spinup and spindown in low and microgravity environments, (2) linear functions of increasing and decreasing gravity environments at high and lowrotating cylinder speeds, and (3) step functions of spinup and spindown in a lowgravity environment.
