Abstract

The interaction of aircraft jet exhaust and wake vortex in numerically studied. Following the preceding numerical study of wake vortex evolution from roll-up until vortex decay, we aim to simulate the jet-vortex interaction from the early phase until the complete roll-up. For numerical simulation we employ an unstructured mesh Reynolds-averaged Navier-Stokes (RANS) solver for the near-field indluding the boundary lay around an aircraft, while a Cartesian mesh large-eddy simulation (LES) solver implemented on the framework of the Building-Cube Method (BCM) is used for the mid- to fair-field wake development.
