Professor Feng Xiao's research lab specializes in numerical methods for computational fluid dynamics and interface capturing, with a focus on developing high-accuracy, conservative schemes for simulating moving interfaces in multi-fluid systems. The lab pioneers advanced numerical algorithms such as the THINC and CSLR methods, which enable oscillation-free and smearing-free advection of fluid interfaces on structured and unstructured grids. Additionally, the lab explores applications in materials science, including the design of superhydrophobic surfaces for corrosion protection, and investigates physiological mechanisms in ischemia/reperfusion injury, particularly in the context of brain injury and neutrophil dynamics. The research integrates computational science with practical engineering and biomedical applications.

Abstract This paper presents a simple and practical scheme for capturing moving interfaces or free boundaries in multi‐fluid simulations. The scheme, which is called THINC (tangent of hyperbola for interface capturing), makes use of the hyperbolic tangent function to compute the numerical flux for the fluid fraction function, and gives a conservative, oscillation‐less and smearing‐less solution to the fluid fraction function even for the extremely distorted interfaces of arbitrary complexity. Th
Anodic CuO nanoneedle array films were synthesized and modified by fluorosilanization to create superhydrophobic surfaces for effective corrosion protection.
In this paper, we present two practical schemes for advection transport equation. The schemes, namely Conservative Semi‐Lagrangian with Rational function (CSLR0) and CSLR1, are two new variants of the Constrained Interpolation Profile‐Conservative Semi‐Lagrangian (CIP‐CSL) type methods [ Yabe et al. , 2001 ]. In these schemes, the subgrid profile is approximated within a single cell by rational interpolation functions. Both the cell‐integrated average and the values at the two cell interfaces ar
SUMMARY We present in this paper an efficient and accurate volume of fluid (VOF) type scheme to compute moving interfaces on unstructured grids with arbitrary quadrilateral mesh elements in 2D and hexahedral elements in 3D. Being an extension of the multi‐dimensional tangent of hyperbola interface capturing (THINC) reconstruction proposed by the authors in Cartesian grid, an algebraic VOF scheme is devised for arbitrary quadrilateral and hexahedral elements. The interface is cell‐wisely approxim
