Liquid sloshing in ship tanks would have a direct effect on dynamic stability, and thus is of great importance for navigation safety. To calculate the sloshing-induced force real tanks, this paper presents an approach to numerically simulate liquid-sloshing complex using moving particle semi-implicit (MPS) method. The calculated used investigate different excitation conditions which realistic m...

Application of computation in many fields are growing fast in last two decades. Increasing on computation performance helps researchers to understand natural phenomena in many fields of science and technology including in life sciences. Computational fluid dynamic is one of numerical methods which is very popular used to describe those phenomena. In this paper we propose moving particle semi-im...

Lagrangian particle-based methods have opened new perspectives for the investigation of complex problems with large free-surface deformation. Some well-known adopted to solve non-linear hydrodynamics are smoothed particle (SPH) and moving semi-implicit (MPS). Both modeled continuum by a system particles (points) but adopting distinct approaches numerical operators, pressure calculation, boundar...

Medical and engineering technologies have developed the surgical simulators, which allow users to train for surgical skills. To perform the aortic valve replacement, which is one of the cardiovascular surgeries, it is necessary to examine not only the timing of the heart pulsating but also the stress distribution on the aortic valve. For pre-operative planning, we have visualized the stress on ...

Abstract—This paper presents a fully Lagrangian coupled Fluid-Structure Interaction (FSI) solver for simulations of fluid-structure interactions, which is based on the Moving Particle Semi-implicit (MPS) method to solve the governing equations corresponding to incompressible flows as well as elastic structures. The developed solver is verified by reproducing the high velocity impact loads of de...

The progress status of jet-grouting construction during the phase is difficult to verify and even after completion construction, it can be verified only by empirical methods. This study attempted recreate a realistic simulation result middle-pressure method establishing computer-aided engineering (CAE) system from planning/design stage ground model verifying validity process was analyzed moving...

The Rayleigh-Taylor instability problem is one of the classic hydrodynamic instability cases in natural scenarios and industrial applications. For the numerical simulation of the Rayleigh-Taylor instability problem, this paper presents a multiphase method based on the moving particle semi-implicit (MPS) method. Herein, the incompressibility of the fluids is satisfied by solving a Poisson Pressu...

As a Lagrangian gridless particle method, the MPS (Moving Particle Semi-implicit) method has wide engineering application. However, for complex 3D flows, unphysical pressure oscillations often occur and result in failure of simulations. This paper compares stability enhancement methods proposed by different researchers to develop 3D, stable method. The results indicate that are incapable elimin...

The boiling behavior on nano-structured surfaces is a frontier research direction in nuclear engineering. However, the mechanism of heat transfer still unclear. In this study, depletable micro-layer model and nano-structure are proposed based Moving Particle Semi-implicit (MPS) method coupled with Meshless-Advection using Flow-directional Local-grid (MAFL) scheme, also known as MPS-MAFL method....
