Project Description

The system consists of two different fluids, including water as the primary fluid and one secondary fluid is Air. The Eulerian VOF model has been used. The jet-air is entering the domain with the speed of 24 m/s with gravity considered as -9.81 m/s-2 on the y-axis.

Geometry & Mesh

The 3-D geometry of the present model is carried out using Design Modeler software. The geometry consists two-section, the lower section is resident water, and the upper section contains outlet and velocity inlet; tank sides are considering as well.


The meshing of this present model has been generated by ANSYS Meshing software. The mesh grid is unstructured with no element quality lower than 0.52, and the total cell number is 795842. the figure below shows an overview of the performed mesh.


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 effect of gravity on the flow is considered to be 9.81 m.s-2 and along with the y-axis in the present model.

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

K-omega Viscous model
standard k-omega model
shear flow corrections k-omega options
water primary phase
air secondary phase
explicit formulation
Boundary conditions
Velocity-inlet inlet
0 initial gauge pressure mixture
24 m/s velocity magnitude air
1 volume fraction
Pressure outlet outlet
1 backflow volume fraction air
0 backflow volume fraction water
wall wall
stationary wall wall motion
Solution Methods
Phase coupled pressure-velocity coupling
PRESTO! pressure
first-order upwind momentum
first-order upwind specific dissipation rate
first-order upwind volume fraction
standard initialization method
34 m/s water velocity (0,y,0)
0 m/s air velocity (x,y,z)
1 the secondary phase volume fraction


At the end of the solution process, two-dimensional and three-dimensional velocity, air and water volume fraction, and animation of filling fountain are obtained. The jet-air enters domain from nozzle shape inlet by time develops jet flow and impacts resident water. The result shows water sliding insides and making vortex on the surface—jet flow after losing kinetic energy vent out from pressure outlet.

You can obtain Geometry & Mesh file and a comprehensive Training Movie which presents how to solve the problem and extract all desired results.
