AWG ERIF Test Case 12: Single Rotating Fan Blade
Image: | |
Description: | Comparison of results from different cpu architectures for a single rotating fan blade. The model demonstrates a stable solution for the rotation of a blade. Specifically, the blade internal and kinetic energy should remain constant as the blade is rotated. An implicit analysis is required first to apply the rotational centrifugal load or preload to the blade. This analysis is followed by an explicit rotation of the blade where the stability of the blade internal and kinetic energies are evaluated. The implicit and explicit analysis are completed in one-step analysis by using the keyword input *CONTROL DYNAMIC RELAXATION with IDRFLAG=5. |
Sub Test Case 1 uses a solid element discretization for the fan blade. | |
Sub Test Case 2 uses a shell element discretization for the fan blade. | |
Sub Test Case 3 uses a thick shell element discretization for the fan blade. | |
Status: | Accepted and currently part of the AWG Test Suite |
