Water Spraying from the Roof of the Greenhouse

Water Spraying from the Roof of the Greenhouse, Ansys Fluent CFD Simulation Training

In this project, water spraying from the greenhouse’s roof has been simulated, and the simulation results have been investigated by ANSYS Fluent software.

The present model is designed in two dimensions using Design Modeler software. The geometry consists two-section, the lower section is resident water, and the upper section contains an outlet and velocity inlet; tank sides are considered walls.

The meshing of the model has been done using ANSYS Meshing software. The element number is 208921. Also, due to the nature of the present problem, the transient solver has been enabled.

Water Spraying Methodology

The system consists of two different fluids, including air as the primary fluid and one secondary fluid, water. The Eulerian multiphase model has been used.

The water jet enters the domain with a velocity of 0.3 m/s with gravity considered as -9.81 m/s2 on the y-axis. Moreover, the SST k-omega model is used to solve turbulent fluid equations.

Water Spraying Conclusion

At the end of the solution process, two-dimensional and three-dimensional velocity, air, and water volume fraction are obtained. This 2-D simulation shows that water starts to pump through the conservatory roof watering system nozzles, drops down, and covers the bottom surface.
