Direct numerical simulation of hydrosol dynamics in turbulent channel flow*

Deposition of Asphaltene particles in crude oil during production/process poses a serious challenge in petroleum industry and has gone unaddressed yet. More specifically, dispersion and deposition of hydrosol (solid particles in a liquid such as asphaltene particles in crude oil) have not been studied extensively, and may have different dynamics compared to widely studied aerosol (solid particles in a gas) dynamics due to different properties of the carrier (fluid) phase such as density. Here we aim to take a foundational step to unveil the major underlying mechanisms of asphaltene particle (hydrosol) deposition process using high fidelity data obtained from Point-Particle Direct Numerical Simulations (PP-DNS). In particular, dispersion and deposition dynamics (e.g., deposition velocity) of hydrosol will be assessed and compared to aerosol when small particles are considered.
