Numerical Simulation of Ethylene Injection from In-Stream Fueling Pylons (Postprint)

Abstract

This paper covers numerical simulation results for an in-stream fuel injector in a Mach number 2.0 flow. Three fuel injection pylon configurations studied are a basic pylon, a ramp pylon, and an alternating wedge pylon. The first pylon configuration is a baseline. The latter two configurations introduce streamwise vorticity into the flow to increase mixing action. Computational Fluid Dynamic simulations with ethylene fuel injection are presented and evaluated. Four parameters used for comparison among the pylons are streamwise vorticity, total pressure loss, mixing efficiency, and flammable plume extent. An overall energy comparison is also accomplished. It is found the two pylons with streamwise vorticity generation are better mixing devices that have an energy advantage over the baseline for a finite distance downstream of the pylon.
