Abstract

The current work aims to study the influence of the numerical setup on a URANS model of a single co-axial injection element under acoustic forcing. The single injector model is representative of an experimental rocket combustor with multiple injection elements, named BKH and operated at DLR Institute of Space Propulsion. The configurations presented in this work are fully 3D for the 1L and 1T mode excitation and compared with previous configurations.14, 34The flame zone is studied with an unstructured and hybrid mesh. An influence of the numerical setup is visible.
