Spraying Project Description
In this study, spraying in human lungs was investigated using the one-way DPM (Disctere phase material) method using Ansys Fluent software. In this simulation, two types of material are used: air and particles that enter the lungs in a Disctere phase material. Trajectories of particles within the lung were observed using Ansys Fluent software. The air inlet velocity enters the field at 5 m / s with a gravity of -9.81 m / s-2 on the z-axis.
Geometry & Mesh
The 3-D geometry of the present model is carried out using Spaceclim software. The inlet diameters of the Lugs are 50 cm.
For grid generation, unstructured mesh with 3734238 elements in the Ansys Meshing software was utilized. The curvature Method was used to focus on grid-sensitive areas. The following figure shows the mesh generation for this problem.
Spraying CFD Simulation
To simulate the present model, we consider several assumptions:
- The solver is pressure-based.
- The present simulation is performed as the steady-state.
- The gravity effect is equivalent to -9.81 m.s-1.
For solving the above problem, RANS Includes discrete phase particles by integrating the force balance on the particles, which is written in a Lagrangian reference frame. This force balance equates the particle inertia with the forces acting on the particle.
Here is a summary of the steps for defining the problem and its solution in the following table:
|Standard wall Function||Wall function|
|Discrete phase model (DPM)|
|Injection type:||Surface velocity inlet|
|Total flow rate:||0.1/s|
|Outlet 1||Pressure outlet||0 pa
|Outlet 2||Pressure outlet||0 pa
|Wall flow||wall||stationary wall
|Coupled||pressure velocity coupling|
|First-order upwind||turbulent kinetic energy|
|First-order upwind||turbulent dissipation rate|
Finally, extract the amounts of outlet velocity and pressure. In addition, we see Particle tracking in the lungs.
