Investigations of dynamics and structure generation in jet-in-crossflow con-figurations

当集中的强射流沿壁面向边界层流动注入能量时，会遇到横流射流构型。这导致了迄今为止无法解释的射流和横流之间的相互作用，其依赖于定义配置的参数需要澄清。利用稳定性理论的数值模拟和研究旨在对射流和横流构型的流体动力学机制有一个新的认识，这对更好地理解和优化这类构型是必要的。在本提案的第一个资助期内，来自最新文献的必要数值工具已扩展到可压缩流动并得到验证。利用这些，现在将研究超声速流动中的新结构，目前还没有研究和发现。

Jet-in-crossflow configurations are encountered when a concentrated strong jet injects energy into a boundary-layer flow along a wall. This leads to hitherto unexplained interactions between jet and cross flow, whose dependence on the parameters defining the con-figuration needs to be clarified. Numerical simulations and investigations using stability theory are intended to lead to a new insight into the fluid-dynamical mechanisms of jet-and-crossflow configurations which are needed for a better understanding and optimization of such configurations. The necessary numerical tools from the most recent literature have been extended to and validated for compressible flows in the first funding period of the present proposal. Using these, new configurations in supersonic flow shall now be in-vestigated, for which neither investigations nor findings are available so far.
