Rotating Detonation Engine experimentation. Laser and non-laser optical flow diagnostics. Sponsor: Aerojet Rocketdyne, Inc. (2016 – 2018)Applied various time-resolved optical and laser diagnostic techniques, namely OH* Chemiluminescence, and Particle Image Velocimetry (PIV) to successfully characterize combustion and supersonic flow behavior within a methane fueled RDEDeveloped programs to generate post-processed data for immediate post-test performance metricsRefined data analysis tools to reconstruct and phase average cyclic data from PIV imagesDesigned plumbing, electrical, and diagnostics systems for RDE experiments in an 18’x 8’ space

Wright-Patterson Afb, Dayton, Ohio

Responsible for flow stand experiments testing discharge coefficients of combustor sections and related components.Reported key results and provided team write-ups to support both the experimental and computational teams.

Wright-Patterson Afb, Dayton, Ohio

Utilized Ansys Fluent to run simulations for Computation Fluid Dynamic analysis of Ultra-Compact Combustors (UCCs) and applicable subsystems. Aided research engineers by conducting reacting and non-reacting RANS simulations of UCCs and post-processed results from fluid flow simulations. Written results reported.Gained an introductory understanding of turbulent behavior of fluids during the combustion process and flame stability effects from fuel-lean equivalence ratios.

Dayton, Ohio Area

Senior Capstone Project:Managed team progress, created testing methods for thrust and specific fuel consumption, post-processed results from on-site testing at WPAFB. Created a conceptual and preliminary design for an inlet mounted water injection system (over-spray) for the JetCat P90 gas turbine engine to increase component efficiency at military power. Results yielded a nominal efficiency increase and a thrust increase.
