Abstract
An unstructured, shock-fitting algorithm, originally developed to simulate inviscid flows, has been further developed to make it capable of dealing with shock-wave/boundary-layer interactions (SWBLI). This paper illustrates the newly implemented algorithmic features of this technique and its application to two-dimensional flow-configurations representative of three different SWBLI patterns. A detailed comparison between the numerical solutions obtained using the aforementioned shock-fitting and a “state-of-the-art” shock-capturing technique on nearly identical meshes are also given. More specifically, qualitative and quantitative grid-convergence analyses are presented to show the significant achievements in terms of reduced discretization error and improved order-of-convergence that shock-fitting delivers, compared to shock-capturing.
