A&A Monday Seminar with Fiona Spencer, UW Applied Physics Lab
High-performance mixing in a novel chemical rocket engine, Abstract
A conventional liquid rocket engine mixes its propellants through an injector plate, a showerhead of hundreds of small elements that is among the most complex, costly, and failure-prone parts of the engine, and whose face sits exactly where chamber acoustics couple to heat release. This talk examines a different approach: inject fuel and oxidizer as two radial wall jets near the upstream end of the chamber and let the chamber-scale counter-rotating vortex pair they spin up do the mixing. The idea is motivated by results from pulsed chemical lasers, confined transverse-jet experiments, and the UW rotating detonation engine.
Using direct numerical simulation and large-eddy simulation of inert surrogate propellants, together with confined mixing theory, I will show that the vortex pair produces a nearly uniform mixture within about one chamber diameter of the inlets, with concentration fluctuations decaying as the theory predicts and no…
