Week 9- Unsteady moving zones Approach

Aim

To simulate the motion of blades in a generic turbomachinery component using an unsteady approach assuming the blade rotation at 300 rpm.

Procedure

The 2-d diagram had 3 domains ,all of them were put together in FLUENT.

The viscous model used for both is k-epsilon realizable.

RPM - 300

a.Moving reference approach

1.Solver- Pressure based

Time-Steady

Velocity-Absolute

b.Moving mesh approach

1.Solver- Pressure based

Time-Transient

Velocity-Absolute

Result

The motion of blade was simulated in a generic turbomachinery component using an unsteady approach and required plots and contours has been shown above .
