Volume-of-Fluid (VOF) and, more generally, Moment-of-Fluid (MOF) methods have proven effective in capturing the evolution of complex two-phase flows such as atomizing liquid sprays, thanks to their unique ability to exactly conserve local volume. However, current VOF\/MOF methods are (at best) limited to second-order accuracy, constrained by a combination of reconstruction, representation, and integration errors of order two or less. In this talk, I will present recent developments towards a high-order three-dimensional VOF\/MOF framework built on two key advances: (1) a semi-Lagrangian formulation for transporting geometric moments of fluid of arbitrarily high order, and (2) the use of piecewise-parabolic interface reconstructions instead of traditional piecewise-linear ones to increase the order of accuracy of the moment transport. This approach retains the geometric and conservative strengths of traditional VOF\/MOF methods while enabling higher accuracy.<\/p>\n<p><strong>Bio: <\/strong>Fabien Evrard is an Assistant Professor of Aerospace Engineering at the University of Illinois Urbana-Champaign.
