Twodimensional modeling of capillary liquid flow in a thin annulus
Abstract
A model for the flow in a thin annular cylinder such as a spacecraft fuel tank or cooling system, is developed. The model assumes that only azimuthal and axial directions are important; the flow in radial direction is negligible. The model uses the Euler equations, solved numerically by the code ANVOF. Examples to illustrate the method include one in which a tank performs a slew maneuver and the influence (i.e., force, torque, location of the center of mass) of the liquid on the tank is calculated.
