In this work, we study hyperbolic conservation law in one space dimension with δ-singularities as the initial data. We use finite volume methods to find the sizes of pollution region.

Foam injection is a promising method to improve sweep efficiency for gas flooding in enhanced oil recovery (EOR). The effect of oil on foam is a complex phenomenon and for this reason three phase foam simulations have shown to be difficult in the past. Initially the objective of this simulation study was getting a better understanding of relating composition paths for foam displacements on the ...

Abstract Dendritic deformation induced by convection of thermal fluid is one the factors leading to dendrite fragmentation and plays a crucial role in grain structure alloy, which lacks in-depth understanding.

In recent years, forest fires and maritime accidents have occurred frequently, which had a bad impact on human production life. Thus, the development of seaplanes is an increasingly urgent demand. It important to study taxiing process for seaplanes, strong nonlinear fluid-structure interaction problem. this paper, Smoothed Particle Hydrodynamics (SPH) method based Lagrangian framework utilized ...

Silica aerogels are highly porous 3D nanostructures and have exhibited excellent physio-chemical properties. Although silica aerogels have broad potential in many fields, the poor mechanical properties greatly limit further applications. In this study, we have applied the finite volume method (FVM) method to calculate the mechanical properties of silica aerogels with different geometric propert...

Moving-mesh unstructured Finite Volume Method (FVM) is a good candidate for tackling flow simulations where the shape of the domain changes during the simulation or represents a part of the solution. For efficient and user-friendly approach to the problem, it is necessary to automatically determine the point positions in the mesh, based on the prescribed boundary motion. In this paper, we prese...

Computational fluid dynamics (CFD) applies numerical methods to solve transport phenomena problems. These include, for example, problems related flow comprising the Navier–Stokes equations either compressible or incompressible fluids, together with turbulence models and continuity single multi-component (reacting inert) systems. The design space is first segmented into discrete volume elements ...

Finite volume methods (FVM) and finite element methods (FEM) are popular tools to solve the parabolic partial differential equation describing the propagation of the electrical impulse in the heart muscle. This report demonstrates that these formulations are indeed equivalent provided that (1) linear elements are used for the FEM, and (2) the mass matrix is lumped. As a consequence, exact local...

This paper takes a typical 220 kV three-phase three-limb oil-immersed transformer as an example, this paper building transient field-circuit coupled model and 3D coupled magneto -fluid-thermal model. Considering a nonlinear B–H curve, the magneto model uses the field-circuit coupled finite element method (FEM) to calculate the magnetic flux distribution of the core and the current distribution ...
