Abstract/Description: The Moment-of-fluid method introduced by Dyadechko and Shashkov is a technique for numerically representing deforming boundaries in a localized manner. Because of the "locality" property of the Moment-of-fluid representation, the symmetric difference error for the Moment-of-fluid piecewise linear reconstruction algorithm is smallest among volume tracking algorithms. The novelty of the Moment-of-fluid method, when compared to standard volume-of-fluid methods, is that both the zeroth and first moments are discretized. A natural extension of the piecewise linear moment-of-fluid method is to increase the order of the incorporated moment data so that a higher order interface can be reconstructed. In this paper, we present a quadratic moment-of-fluid method that reconstructs a second-order level set approximation from zeroth, first, and second moments. The novel Quadratic Moment-of-fluid algorithm, herein described and developed, is expected to lead to significantly more accurate computational fluid dynamics algorithms for multiphase flows with prominent surface tension effects. The surface tension force is proportional to the interface curvature. The interface curvature, derived from the piecewise parabolic interface reconstruction, is expected to be approximated with much improved accuracy to that derived from the piecewise linear moment-of-fluid reconstruction.
