The study is concentrated on the analysis of the interaction between oil wells and water-induced hydraulic fractures. The problem is considered in terms of theory of poroelasticity, hydrodynamics and fracture mechanics. The hydrodynamic aspect of the problem is divided into two types: oil displacement by water injected and the study of water behaviour inside the fracture itself. Numerical modelling...
Two different boundary condition treatments-mirror boundary conditions and static boundary conditions are implemented to simulate lid-driven cavity flow with incompressible SPH (ISPH) algorithms. The algorithms include density-invariant ISPH (ISPH-DI) and divergence-free ISPH (ISPH-DF). The results show that simulations are more accurate with the static particles boundary and the ISPH-DF algorithm...
Small scale multiphase fluid motion is fundamentally important for applications in environmental, biological and chemical engineering as well as many other areas. Due to the existence of complex geometries, arbitrarily moving interfaces, and large density and viscosity contrast, simulation of small scale multiphase flows has been a formidable task for traditional grid-based numerical methods. This...
Two-phase flow problems are presented using the method of smoothed particle hydrodynamics (SPH). The combination of meshless and lagrangian nature inherent in the SPH method offers the advantages in treating large deformations, large inhomogeneities and tracing interfaces in the two-phase flow process. Two cases are solved using a SPH code developed at ACES. It is found that major physics of the two-phase...
We present several new methods to promote the ship simulator applied to both physically and graphically real-time dynamic rendered ocean. The simulation system is divided into three subsystems, the ships dynamics system, the hydrodynamics system, and two ways coupling between them. We apply hydrodynamic and mechanics to simulate the ocean surface and ship model respectively. In this paper, wave decay...
