چکیده
Due to the convenience and flexibility in modeling complex geometries deformable objects, local ghost particles methods are becoming more popular. In present study, a novel semi-fixed method is proposed for weakly compressible smoothed particle hydrodynamics (WCSPH). comparison with previous methods, new boundary can effectively reduce spurious pressure oscillations smooth flow field. Besides, generation mechanism of fictitious simple robust, which suitable all kinds kernel functions different sizes support domain. The numerical accuracy stability (SPH) scheme validated several typical benchmark cases. A detailed investigation into on solid walls surface elevation dynamic simulations also conducted. results shows that helps solutions improves

A ghost-cell immersed boundary method for inviscid compressible flows
An immersed boundary method (IBM) is presented, that can be applied to inviscid compressible flows, described by the full-potential or Euler equations, to start with. Possible applications that we envisage are preliminary aircraft design and rotor-flow computations. Although Navier-Stokes methods have improved significantly in the last three decades, and although computations with the latter eq...
متن کاملA Boundary Meshless Method for Neumann Problem
Boundary integral equations (BIE) are reformulations of boundary value problems for partial differential equations. There is a plethora of research on numerical methods for all types of these equations such as solving by discretization which includes numerical integration. In this paper, the Neumann problem is reformulated to a BIE, and then moving least squares as a meshless method is describe...
متن کاملNvestigation of a Boundary Layer Problem for Perturbed Cauchy-Riemann Equation with Non-local Boundary Condition
Boundary layer problems (Singular perturbation problems) more have been applied for ordinary differential equations. While this theory for partial differential equations have many applications in several fields of physics and engineering. Because of complexity of limit and boundary behavior of the solutions of partial differential equations these problems considered less than ordinary case. In ...
متن کاملA novel local search method for microaggregation
In this paper, we propose an effective microaggregation algorithm to produce a more useful protected data for publishing. Microaggregation is mapped to a clustering problem with known minimum and maximum group size constraints. In this scheme, the goal is to cluster n records into groups of at least k and at most 2k_1 records, such that the sum of the within-group squ...
متن کاملA hybrid method for singularly perturbed delay boundary value problems exhibiting a right boundary layer
The aim of this paper is to present a numerical method for singularly perturbed convection-diffusion problems with a delay. The method is a combination of the asymptotic expansion technique and the reproducing kernel method (RKM). First an asymptotic expansion for the solution of the given singularly perturbed delayed boundary value problem is constructed. Then the reduced regular delayed diffe...
