Multicomponent Particle Project Description
In this project, the Multicomponent particle type for droplets has been investigated by Ansys Fluent software. We used the one-way DPM to simulate the discrete phase.
Geometry & Mesh
The 3D geometry of this project has been produced with Spaceclaim software. The length of the computational area is 100 mm, and its height & width is 20 mm.
Mesh is created with Ansys Meshing software and the mesh type is unstructured. The number of cells is 56245.
To simulate the present model, we consider several assumptions:
- The solver is pressure-based.
- The current simulation is unsteady in terms of time.
- We ignored the gravity effect.
Here is a summary of the steps for defining the problem and its solution in the following table:
|Viscous model||K-w SST|
|particle treatment||unsteady particle tracking|
|material in injection||Hydrogen_peroxide_water|
|particle type in injection||multicomponent|
|discrete phase BC type||Escape|
|discrete phase BC type||escape|
|wall motion||stationary wall|
|discrete phase BC type||reflect|
|Modified turbulent viscosity||first-order upwind|
Multicomponent particle Results
In this simulation, which is injected by an injector droplet of two mixed species, which is water and hydroperoxide, the type of evaporative water is defined and the second type without evaporation is considered for this reason. As it is clear from the results, the evaporation of a species can be seen in the droplets and the decrease in the diameter of the droplets can be seen.
You can obtain Geometry & Mesh file and a comprehensive Training Movie that presents how to solve the problem and extract all desired results.
