We develop a new simulation method of colloidal suspensions, which we call a "fluid particle dynamics" (FPD) method. This FPD method, which treats a colloid as a fluid particle, removes the difficulties stemming from a solid-fluid boundary condition in the treatment of hydrodynamic interactions between the particles. The importance of interparticle hydrodynamic interactions in the aggregation p...

The characterization of many objects involves the determination of a basic set of particle size measures derived mainly from scattering and transport property measurements. For polymers, these basic properties include the radius of gyration Rg, hydrodynamic radius Rh, intrinsic viscosity [η], and sedimentation coefficient S, and for conductive particles, the electric polarizability tensor αE an...

Waves exert one of the most important forces on offshore and coastal structures as well as floating vessels. However, due to the random nature of waves, estimation of their hydrodynamic forces on marine structures is very complicated. Morison's semi-empirical model, is one of the models capable of estimating wave forces on slender cylindrical elements of marine structures. In this research usin...

With advances in anisotropic particle synthesis, particle shape is now a feasible parameter for tuning suspension properties. However, there is a need to determine how these newly synthesized particles affect suspension properties and a need to solve the inverse problem of inferring the particle shape from property measurements. Either way, accurate suspension property predictions are required....

a r t i c l e i n f o a b s t r a c t We introduce a massively parallelized test-particle based kinetic Monte Carlo code that is capable of modeling the phase space evolution of an arbitrarily sized system that is free to move in and out of the continuum limit. Our code combines advantages of the DSMC and the Point of Closest Approach techniques for solving the collision integral. With that, it...

In this work, the effects of the scattering angle on the nonexponentiality of the normalized time auto-correlation function of the scattered light intensity g (τ ) are investigated using dilute Poly(N-isopropylacrylamide) microgel and standard polystyrene latex samples in dispersion respectively. The results show that the influences of the scattering angle on the deviation between an exponentia...

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...
