| Abstract | Publisher Summary With the advent of inexpensive parallel computers, state-of-the-art modeling strategies for simulating turbulent and transitional flows—that is, direct numerical simulations (DNSs) and large-eddy simulations (LESs)—are continuously expanding into new areas of applications. Particularly, attractive examples, from the perspective of the required spatio-temporal resolution, are from the field of medicine and biology, where in most cases, transitional and low Reynolds numbers flows are of interest. The challenge in this case, however, is to properly account for the complex fluid-structure interactions that dominate the dynamics of these flows. The use of numerical methods based on unstructured grids is a possibility, but usually the transition to parallel platforms is fairly complex. Mesh partition, load balance, and the inversion of large sparce matrixes are the most commonly encountered bottlenecks in efficient parallelization. In most cases, the intrinsic dissipative discretizations make them problematic in DNS and LES. |
