Watering the Lawns Project Description
The system consists of two different fluids, including air as the primary fluid and one secondary fluid is water. The Eulerian multiphase model has been used by ANSYS Fluent software. The jet-air is entering the domain with the speed of 0.5 m/s with gravity considered as -9.81 m/s-2 on the y-axis.
Geometry & Mesh
The 2-D geometry of the present model is carried out using Design Modeler software.
The meshing of this present model has been generated by ANSYS Meshing software. The mesh grid is unstructured with no element quality lower than 0.54, and the total cell number is 19203911.
Watering the Lawns CFD Simulation
To simulate the present model, several assumptions are considered, which are:
- The solver is pressure-based and Transient.
- 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.

Watering the Lawns Results
At the end of the solution process, two-dimensional and three-dimensional velocity, air and water volume fraction, and animation are obtained. This 2-D simulation show water starts to flow from the sprinkler nozzle and reaches the spreader fin, and by time passing, it comes to the surface of the earth, and water cover’s it.
