Week 9- Unsteady moving zones Approach

AIM: To simulate the motion of blades in a generic turbomachinery component using an unsteady approach.

OBJECTIVE:

• Assume blade rotation at 300rpm
• Choose an appropriate time step for the simulation and generate an animation file for the rotation.

SETUP & SOLUTION:

• Import the mesh file in the fluent as shown below,

• Use the Moving Frame method for the simulation first and follow the steps in the video to set up the simulation.
• General Settings

• Cell zone conditions as follows:

• Assume blade rotation at 300rpm:

• Boundary condition as follows:

• Finally, the solution model:

RESULT:

For Frame Motion Method:

• RESIDUAL:

• MASS FLOW RATE:

• PRESSURE CONTOUR:

• VELOCITY CONTOUR:

Results For Mesh Motion Method:

• RESIDUAL:

• PRESSURE CONTOUR:

• VELOCITY CONTOUR:

• ANIMATION FOR PRESSURE:

• ANIMATION FOR VELOCITY:

CONCLUSION:

• Hence the simulation of the motion blades in a generic turbomachinery component using an unsteady approach is done.
