Feng Xiao 교수의 연구실은 다상유체 유동에서의 자유경계 및 인터페이스를 정확하고 안정적으로 추적하는 수치해법을 핵심으로 하며, 특히 THINC(탄젠트 hyperbola를 이용한 인터페이스 캡처) 기반의 고정밀 보존형 수치기법을 개발하고 있습니다. 이는 유체 분율 함수의 오scillation 및 스며임 현상을 최소화하여 복잡한 기하학적 경계 조건에서도 뛰어난 수치적 안정성을 확보합니다. 또한, 비정규 메esh에서의 정확한 인터페이스 추적과 초음파, 생체유체역학 등 응용 분야로의 확장도 진행 중입니다. 연구는 수치해석, 유체역학, 생체공학 등 다학제적 접근을 기반으로 하고 있습니다.

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.

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
