An Algorithm based on Predicting the Interface in Phase Change Materials
Phase change materials are substances that absorb and release thermal energy during the process of melting and freezing. This characteristic makes phase change material (PCM) a favourite choice to integrate it in buildings. Stephan problem including melting and solidification in PMC materials is an practical problem in many engineering processes. The position of the moving boundary, its veloci...
متن کاملMulti-materials with strong interface: Variational modelings
We introduce a simplified model for a multi-material made up of two elastic bodies connected by a strong thin material layer whose stiffness grows as 1 . The model is obtained by identifying the Γ-limit of the stored strain energy functional of the physical problem when the thickness of the intermediate layer tends to zero. The intermediate layer behaves as a stiffening elastic membrane. Furthe...

متن کاملAn Energetic Variational Formulation with Phase Field Methods for Interfacial Dynamics of Complex Fluids: Advantages and Challenges
The use of a phase field to describe interfacial phenomena has a long and fruitful tradition. There are two key ingredients to the method: the transformation of Lagrangian description of geometric motions to Eulerian description framework, and the employment of the energetic variational procedure to derive the coupled systems. Several groups have used this theoretical framework to approximate N...
متن کاملEnergetic materials: flexible approach pays off.
Despite rapid advances in the design and fabrication of miniaturized sensors and devices, their practical applications have been impeded by the lack of suitably miniscule sources of electrical power. Indeed, the generation and storage of electrical energy for mobile devices and systems is one of the most urgent challenges in science and engineering today. Microand nanoscale devices — such as ul...
