The present study simulates the Firehose by ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

The present model is designed in two dimensions using Design Modeler software. The geometry has an imaginary building on fire, firehose as the inlet.

Also, the firehose geometry is designed based on the standard shape of real firehoses to simulate water flow directly and accurately. Grounds and objects are considered walls, and a round sphere is considered an outlet.

The meshing of the model has been done using ANSYS Meshing software. The element number is 147351.

Also, due to the nature of the present problem, the transient solver is enabled.

Firehose Methodology

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

The water enters the domain with a velocity of 9 m/s with gravity considered as -9.81 m/s2 on the y-axis. Moreover, the realizable k-epsilon model is used to solve turbulent fluid equations.

Firehose Conclusion

At the end of the solution process, two and three-dimensional contours related to the velocity, water volume fraction, and eddy viscosity are obtained.

As seen in the water volume fraction contour, water starts to flow from the firehose nozzle toward a cylinder-shaped object. It finally hits and covers it with water to burn the imaginary fire. The whole simulation takes action about 1.2 seconds long.
