Full Potential Calculations With Immersed Boundary Ghost-Cell Method

To address the need to simplify the grid generation process while enabling affordable multidisciplinary aerodynamic simulations, this paper presents a novel medium-fidelity unstructured finite volume Full Potential method incorporating an immersed boundary (IB) formulation with ghost cells. The development begins with the classical body-fitted (BF) Full Potential approach, followed by the integration of the IB ghost-cell methodology. Results obtained using the new approach are compared with those from traditional Full Potential and Euler BF methods. The agreement between the solutions demonstrates that the proposed approach offers sufficient accuracy for use in multidisciplinary contexts. Additionally, computational speedups are observed for certain configurations, showcasing significant reduction in computational cost.
