Moving boundary problem is a class of physical problems where the boundaries or interfaces of the domain change with time. In such problems, the boundary positions are not known a priori and have to be determined as a part of the solution. Solving moving boundary problems poses great challenges to both modelling and simulation. From the modelling perspective, moving boundary problems normally involve complex physical mechanisms, such as damage evolution, crack propagation, phase change, chemical erosion, etc. In terms of numerical simulation, a robust algorithm is needed to track the moving boundaries accurately and efficiently.
Moving boundary problems are often associated with Thermal-Hydraulic-Mechanical-Chemical (THMC) coupling processes, and are commonly encountered in a wide range of engineering applications. Despite its theoretical and practical importance, a number of open questions still exist due to the complexity of modelling, simulation and experiments. Hence, advances should be made to deepen our understanding of this research field.
The aim of this Research Topic is to bring together original research articles and review articles highlighting recent advances in theoretical modelling, numerical simulation and laboratory experiments in moving boundary problems of multi-physics coupling processes in engineering. Research integrating machine learning or data-driven techniques is particularly welcome. We also encourage submissions that investigate interesting engineering applications involving moving boundary problems.
Potential topics include but are not limited to the following:
• Machine learning techniques in moving boundary problems;
• Novel theoretical model or constitutive equation for predicting boundary evolution;
• Novel experimental observations related to the moving boundary problems;
• The numerical algorithms for alleviating meshing burden in moving boundary problems, such as extended finite element methods, boundary element methods, meshfree methods, smoothed finite element method, isogeometric analysis, phase field method, etc.
