Gas Particle Movement Through the Nozzle, CFD Simulation Tutorial by Ansys Fluent

This simulation is modeling gas-particle movement through the convergence-divergence nozzle by a Two-way DPM model in Ansys fluent software. The nozzle is in grossly overexpanded condition. These kinds of nozzles are used in the gas and petrochemical industry.

Geometry & Mesh

The 3-D geometry of the present model is carried out using Design Modeler software.

Gas Particles

The meshing of this present model has been generated by ANSYS Meshing software. The mesh grid is unstructured, and the total cell number is 16245216.

Gas Particles Movement CFD Simulation

To simulate the present model, several assumptions are considered, which are:

  • The solver is pressure-based.
  • Simulation has only examined fluid behavior; in other words, heat transfer simulation has not been performed.
  • The gravity effect is ignored.

The following is a summary of the steps for defining the problem and its solution

K-epsilon Viscous model

Boundary conditions
Velocity-inlet inlet
Discrete phase pressure escape
448000 initial gauge pressure
5 m/s velocity magnitude water
Pressure outlet outlet
Discrete phase condition Escape
0 Supersonic gage pressure water

Solution Methods
Phase coupled pressure-velocity coupling
PRESTO! pressure
first-order upwind momentum
first-order upwind specific dissipation rate
first-order upwind volume fraction
hybrid initialization method
52 m/s water velocity (0,y,0)
0 m/s particle velocity (x,y,z)


At the end of the solution process, two-dimensional and three-dimensional velocity and static enthalpy and turbulence kinetic energy are obtained. This 3-D simulation shows how gas particles enter the nozzle from the inlet and travel through a nozzle and how the nozzle effect particle velocity in other simulation conditions.
