Sea Robot Motion Immersed in the Water, Dynamic Mesh, ANSYS Fluent Tutorial

In this project, the moving of a Sea Robot Motion Immersed in Water by the dynamic mesh method is simulated 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 meshing of the model has been done using ANSYS Meshing software. Moreover, the element number is 30010.

Also, the transient solver has been enabled due to the dynamic mesh option.

Robot Methodology

In problems where the location and shape of computational cells change, it is mandatory to use the dynamic mesh model to prevent the extreme deterioration of elements’ quality.

Smoothing and remeshing methods create higher-quality elements when the previous ones may cause errors and are no longer useful to perform calculations with. Remeshing occurs every 50 iterations to generate a new high-quality mesh.

The robot (cube) is first placed on the left side of the domain and moves toward the inlet boundary using an imposed velocity profile (velocity in the X-direction equal to 3 m/s for 0 to 3 seconds).

The standard k-epsilon model was used to solve the turbulent fluid equations. Also, the water enters the rectangular computational domain with a velocity of 1.5 m/s.

Robot Conclusion

At the end of the solution process, two-dimensional contours related to the velocity, pressure, turbulent viscosity, and streamlines inside the computational domain are obtained.

The contours related to pressure clearly show how the robot’s motion against the water flow direction causes the pressure at the stagnation point to increase.

Furthermore, by viewing the contours related to velocity and streamlines, one can easily understand that the opposite motion of the robot concerning the water flow direction will give rise to the wake region occurring behind the robot.
