The problem simulates two-phase flow as soluble particles in a given fluid in a channel with a convergent-divergent structure by ANSYS Fluent software.
The current model is designed in three dimensions using Design Modeler software. The model consists of a channel with a rectangular cross-section with dimensions of 0.001 m * 0.0002 m, which in its longitudinal direction, the geometric structure of the model becomes convergent-divergent.
The meshing of the present model has been done using ANSYS Meshing software. The mesh type is structured, and the element number is equal to 175,500.
The Eulerian multiphase model has been used to simulate the present model. The Eulerian multiphase model is considered the most complex model for defining multiphase flows.
This model solves a set of momentum and conservation equations for each phase separately, While the multiphase mixture and VOF methods only solve the equations for phases other than the initial phase.
We apply the Eulerian model in applications such as bubble columns, droplet flows, particle-laden flows with a volume fraction greater than ten percent, pneumatic transitions for granular liquid flows, fluidized beds for solid-gas slurry flows, particle suspension and sedimentation phenomena as solid-liquid flows.
In this simulation, the base fluid is defined as a liquid with a density of 1050 kg/m3 and a viscosity of 0.000024997 kg/m.s, and the secondary fluid in the form of particles with a density of 1050 kg/m3 and a viscosity of 1. kg/m.s is defined.
The type of particle dispersion in the base liquid is defined in granular form, and the particle diameter is defined as 0.00002 m. The base fluid and its soluble particles enter this channel at a rate of 0.007142 m/s.
At the end of the solution process, two-dimensional and three-dimensional contours related to the mixing pressure, base fluid velocity, soluble particle velocity, and volume fraction of soluble particles are obtained.
As it is obvious, the maximum velocity occurs in the throat zone since the cross-section is minimum in this section.
