In these simulations, the particles were less dense than the fluid so they tend to go upwards and float on top of the tank, and viscosity was varied between 1 cP and 100 cP, while all other parameters remained constant. Contrary to expectations, increasing the fluid viscosity resulted in fewer particles remaining at the top of the tank and improved particle distribution. This behavior is unexpected, as higher viscosity is typically associated with greater resistance to particle drawdown.
