Colliding of Two Water Jets CFD Simulation, Ansys Fluent CFD Simulation Training

The system consists of two different fluids, including air as the primary fluid and one secondary fluid as liquid water. The Eulerian multiphase model has been used to simulate the Colliding of Two Water Jets. The water enters the domain with a speed of 15m/s with gravity considered as -9.81 m/s-2 on the y-axis.

Geometry & Mesh

The 3-D domain of this simulation has been designed in ANSYS Design Modeler. Domain has to inlet as jet flow entrance and sides as an outlet; also, pipe side is wall boundary,


The meshing of this present model has been generated by ANSYS Meshing software. The mesh grid is unstructured, and the total cell number is 872642.


Colliding of Two Water Jets 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:

standard initialization method
8 m/s water velocity (0,y,0)
15 m/s air velocity (x,y,z)
1 the secondary phase volume fraction

Colliding of Two Water Jets Results

Two high-speed water jet flows start to flow from pipes and begin to move toward each other; after jets reach each other, the impact sum of velocity magnitude becomes zero, and water splashes to sides.

At the end of the solution process, two-dimensional and 3-D animation and counters of velocity, air, and water volume fraction are obtained.

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

    Just finished going through the Colliding of Two Water Jets CFD Simulation course. The complexity of the physics involved with dual jet collision was well-illustrated, and the step by step procedure using Ansys Fluent made it easier to follow. Although the simulation only focused on fluid behavior without heat transfer, it was a thorough understanding of the dynamic between different phases within a flow.

    The tutorial really helped me understand the Eulerian multiphase model. However, could you clarify whether any wall treatment was applied in the simulation to account for the fluid’s interaction with the pipe walls?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      In this simulation, a ‘stationary wall’ boundary condition is used to model the fluid’s interaction with the pipe walls. This means that the walls are treated as immovable surfaces that interact with the fluid flow. The mesh is refined near the walls to accurately capture the flow dynamics and wall effects.
