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 theoretical model for estimating Rossiter modes for flow over rectangular cavities for regimes ranging from sub…
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…
Numerical Study of Distorted Tulip Flame Propagation in Confined Systems
Fernando Illacanchi, Sebastian Valencia, Cesar Celis +3
Understanding the dynamics of premixed flames that propagates in confined systems is important in a wide range of applications. The study of premixed flames propagating in a closed…
Fluid Dynamic Simulations of Mach and Regular Reflections in Oblique Shock-Wave Configurations using Adaptive Mesh Refinement
Sebastian Valencia, Cesar Celis, Andres Mendiburu +2
In the context of the interaction between a moving plane shock wave and an inclined wall (wedge), it is possible to distinguish four distinct shock reflection configurations. These…
Assessment of Large Eddy Simulation (LES) Sub-grid Scale Models Accounting for Compressible Homogeneous Isotropic Turbulence
Jhon Cordova, Cesar Celis, Andres Mendiburu +2
Most sub-grid scale (SGS) models employed in LES (large eddy simulation) formulations were originally developed for incompressible, single phase, inert flows and assume transfer of…
