Abstract

The flow around delta wing configurations with rounded leading edges is still not entirely understood. Therefore a second Vortex Flow Experiment – VFE-2 with the RTO/AVT-113 was established, focusing on the flow around delta wing configurations with rounded leading edges. Several experimental data sets were provided and generated within the RTO/AVT-113 task group regarding on a 65° swept delta wing with sharp and different rounded leading edges. The experimental data base is used to expand the knowledge about the flow topology and flow physics and to validate computational codes. This paper is focusing on the flow topology around the VFE-2 delta wing with medium rounded leading edges at different Reynolds numbers and angles of attack. The motivation for using an unstructured grid approach is intended by the simulation of complex realistic fighter configurations especially by taking all control devices and storages into account. The presented investigation is intended as a test to predict the correct physics of the highly complex flow topology of delta wings with rounded leading edge by an unstructured code
