| Sonic and transonic flows are characterized by the presence of shock waves and very strong gradients of pressure, density, and velocity. These flow regimes are common in many engineering applications, such as nozzles, turbomachinery blade passages, and external aerodynamics. Accurately resolving shock waves is essential, as small numerical errors in their prediction can significantly affect the quality of the results.
High-fidelity CFD methods are capable of capturing the complex physics of compressible flows with shocks, but they usually require very fine meshes in shock regions. Classical approaches rely on mesh refinement, which increases the number of grid points and leads to a significant rise in computational cost. An alternative strategy is mesh moving, where the total number of nodes is kept constant and their positions are adjusted to concentrate resolution in regions where shocks occur. This thesis focuses on the application of mesh-moving techniques for high-fidelity CFD simulations of sonic and transonic flows. The goal is to improve shock resolution by relocating mesh nodes according to flow features, instead of increasing mesh density. The student will simulate different flow configurations with shocks and assess the benefits and limitations of mesh moving compared to fixed meshes. |
