The agglomeration and fragmentation of asphaltenes which dictate particle size distribution
(PSD) play an important role in deposition behavior of asphaltene. However, the physics …

In the present paper, a Discrete Element Method-Computational Fluid Dynamics (DEM-CFD)
approach along with a new coalescence model is adopted to study agglomeration and …

Determining the rate of asphaltene particle growth is one of the main problems in modeling
of asphaltene precipitation and deposition. In this paper, the kinetics of asphaltene …

Asphaltene deposition in oil wells greatly causes production and associated monetary
losses. In this work, the virtual mass force and pressure gradient force are considered in the …

A new two-dimensional dynamic model was developed to simulate asphaltene precipitation,
aggregation, and deposition at isothermal and non-isothermal conditions. The perturbed …

Population balance equation is widely used in modeling of particulate processes. In this
work, the enlargement of asphaltene particles in a synthetic heptane-toluene mixture …

Molecular dynamics (MD) simulations were performed to study the occurrence time of each
stage of asphaltene aggregation from single molecules to a large flocculate with and without …

Stokes law is the fundamental equation to describe the settling velocity of a particle for small
Reynolds number flow and is applicable when the particle is spherical and impermeable …

A new population balance model is developed to predict asphaltene fractal aggregates size
distribution. Asphaltene aggregates fractal dimension is increased when shear is induced to …

In this article, the aggregation and breakage processes are simulated through Monte Carlo
method for asphaltene aggregates under shear-induced petroleum mixtures. The simulation …
