Description

Airflow on the Dimpled Rotating Cylinder CFD Simulation, ANSYS Fluent Training

The problem is going to simulate airflow on the Dimpled Rotating Cylinder by ANSYS Fluent software.

A cylindrical object is placed in the channel. The airflow enters the rectangular channel at a horizontal velocity of 0.45 m / s, and it collides with the cylindrical body.

The cylindrical body rotates at an angular velocity of 20 radians per second (rad/s) around the central axis; thus, the moving wall must be defined.

Therefore, the fluid simulation area is divided into two parts, which include the rotating area (having a cylinder with a constant angular velocity) and the area of the fluid (the inner space of the rectangular channel other than the cylinder).

The cylinder wall has dimples whose protruding position is on the inside of the cylinder and whose recess is on the outside of the cylinder.

The aim is to investigate the pressure distribution and rotational phenomena around a rotating cylindrical wall. Therefore, the presence of dimples on the cylinder surface affects fluid behavior.

The geometry of the present model is three-dimensional and is designed using SOLIDWORKS software. The meshing of the present model has been done using ANSYS Meshing software. The mesh type is unstructured and the element number is equal to 1064903.

Dimpled Methodology

Hence, by creating a cylindrical wall in the form of an interface (a common surface between two areas that allows fluid to flow through its boundary), a special flow area in the form of a hollow cylinder around the wall creates a rotating cylinder; thus, the Frame Motion method is used to simulate the internal cylinder area created at the same speed as the angle of rotation of the main cylinder.

Dimpled Conclusion

At the end of the solution process, we obtain contours of pressure, velocity, and turbulence kinetic energy. Using the MRF method, we can assume the cylinder to be constant and the wind flows around the cylinder to be rotating at the same rotational speed of 20 rad/s around the central axis of the cylinder.

The contours show the velocity and pressure distributions in the domain well.
