Liquid fuel hydrocarbon combustion dominates propulsion in the US Air Force and in many aerospace applications. There is considerable cost, regulatory, and environmental pressure toward reducing liquid fuel consumption and converting to sustainable and alternative fuels. The US Air Force Academy (USAFA) has installed a combustion shock tube (CST) for fundamental combustion kinetics, and is actively pursuing the installation of a second CST and a rotating detonation engine (RDE). Complementary computational efforts through USAFA's High Performance Computing Research Center (HPCRC) and collaborations with the Air Force Research Laboratory (AFRL) augment experimental investigations.  Experimental work is carried out at USAFA in Colorado Springs, CO while computational efforts have been split between AFRL in Dayton, OH and USAFA.  Current computational efforts focus on 1D modeling of ignition, and 2D investigations of boundary layer growth in the shock tube using experimental data to inform the models.The HPCRC has historically focused on simulations of aerodynamic phenomena over aircraft bodies. We are seeking to leverage ongoing collaborations with AFRL and faculty at University of Colorado, Colorado Springs (UCCS) to develop and actively fund multiphase reacting flow CFD research capabilities at USAFA. The successful applicant will lead this effort, and will serve as the HPCRC's leading expert in combustion CFD. Research topics will focus on CST and RDE simulations. A hybrid working model is supported and this opportunity is location-flexible.
