| Popis: |
Based on previous experience of the use of different mesh topologies (hexahedral, tetrahedral and hybrid), the present work provides a study on refinement strategies for impingement limits computation. Although hexahedral meshes are more accurate in the representation of surface gradients they require a higher level of user expertise in mesh generation for complex configurations. The grid refinement strategy is based on gradients of volume fraction ( �) relying on the ability of the CFD solver (FLUENT) to maintain mesh quality. Results indicate that the impingement region limits are rather insensitive to mesh choice, but the maximum and averaged collection can vary significantly. Some general levels of equivalency are proposed based on the experiments performed for the DLR-F4 configuration. |
