In smoothed particle hydrodynamics (SPH), an adaptive and meshfree particle method, the particle positions and velocities related to particle interactions must be updated at each time step. Thus, parallel computing is necessary to improve the numerical efficiency for the problems involving large computational domains. For the parallelization of the SPH method, the simulation domain is decompose...

The feasibility of using a Long Short-Term Memory (LSTM) network-driven Non-Intrusive Reduced Order Model (NIROM) to predict the dynamics two-dimensional box floating and interacting with surface water waves is assessed in this study. ground for these wave-structure interactions (WSI) problems, namely displacements hydrodynamic forces arising from wave interaction corresponding particular profi...

A 3-dimensional modified Stokesian dynamics-based technique for simulating mineral particle suspensions is presented. Stokesian dynamics is a mesh free particle approach, which resembles the discrete element method. It includes hydrodynamic interactions and other interparticle forces. Expressions for the hydrodynamic interactions were modified based on results from finite element (FE) calculati...

We present a brief introduction to Smoothed Particle Hydrodynamics SPH where we focus on an approach to treat the physical viscosity Additionally we describe in detail the basic principles of our parallel implementation of the SPH method In the second part we summarise some results of test simulations performed to achieve general features of the method and we end discussing some astrophysical a...

Low-temperature heat capacities from 5 to 350 K by adiabatic calorimetry and high-temperature enthalpy increments above 450 K by drop calorimetry of high-purity Sr(OH), and /I-Ba(OH), have been measured. From the results, smoothed thermochemical and thermophysical functions of the two compounds have been tabulated at selected temperatures.

A particle-dynamics simulation is a tool for investigating nonequilibrium phenomena accompanied with hydrodynamic, thermodynamic motions, and even with phase transitions. In this article, several applications of the particledynamics simulation and a new computational method of particle dynamics are reported.

In this paper, a symmetry particle method, the smoothed particle hydrodynamics (SPHs) method, is extended to deal with non-Newtonian fluids. First, the viscous liquid is modeled by a non-Newtonian fluid flow and the variable viscosity under shear stress is determined by the Carreau-Yasuda model. Then a pressure correction method is proposed, by correcting density error with individual stiffness...

-A two-component smectic undergoing a demixing tran~ition to two coexisting smectic pha~es exhibits a novel spinodal pattern as observed by light ~cattering and optical microscopy. We show that this ~pinodal, characterized by a prescribed angle between the mo~t intense wavevectors and the layer normal, is the result of the instability of the baroclinic mode of two-cojnponent smectic hydrodynamics.
