Generalized Formulation to Predict Rossiter Modes for Subsonic to Hypersonic Flow
Jeremy P. Redding, Luis Bravo, Prashant Khare
This paper describes the development of a generalized physics-based model to accurately estimate Rossiter modes for flow over rectangular cavities for regimes ranging from subsonic…
Hybrid RANS-LES simulation of transverse fuel injection in a Mach-10 scramjet engine
Nick Plewacki, Benjamin Kale, Manu Kamin +1
Hypersonic flight poses unique propulsion challenges, requiring engines that maintain thrust, efficiency, and stability across a wide range of operating conditions. These engines m…
Mutual Interactions Between a Thin Flexible Panel and Supersonic Flows
Himakar Ganti, Luis Bravo, Anindya Ghosal +1
This paper discusses the mutual interactions between a thin flexible aluminum plate and supersonic flow using two-dimensional (2D) numerical simulations. Calculations are performed…
Flow-field analysis and performance assessment of rotating detonation engines under different number of discrete inlet nozzles
Sebastian Valencia, Andres Mendiburu, Luis Bravo +2
This study explores in depth rotating detonation engines (RDEs) fueled by premixed stoichiometric hydrogen/air mixtures through two-dimensional numerical simulations including a de…
Analysis of thermochemical non-equilibrium hypersonic flow over a waverider with uncertainty quantification
Jeremy Redding, Nick Plewacki, Himakar Ganti +2
The objective of this work is to assess the impact of parameter uncertainty on hypersonic aerothermal surface heating predictions in Reynolds-Averaged Navier-Stokes (RANS) simulati…
