description |
The design and off-design studies of hypersonic air-breathing engines
face many challenges because of the complexity of their internal flows.
Mixing and combustion processes in Supersonic-Combustion Ramjet
(scramjet) engines involve complicated aerothermochemical features
such as interactions between shock-waves and boundary-layer, shock
induced-combustion and recirculation zones. In this study, a numerical
solver is developed and validated to be an efficient design tool capable
of simulating these complicated flow features of supersonic combustors.
The flow is solved based on the Reynolds Averaged Navier-Stocks
equations (RANS), beside a chemical kinetics model for the computation
the reactions finite rates. Finite-volume scheme is used where
the convective fluxes are discretized by Roe’s scheme using MUSCL
approach. And, the diffusive fluxes are centrally discretized. Pointimplicit
Runge-Kutta method is applied for time integration. For the
code validation, several test cases are to monitor the code ability to
solve for the different diffusive and turbulent fluxes, and the chemical
source term. In addition, the code is validated by resolving the transverse
sonic injection into supersonic air flow in case of Helium injection
from a flat plate, and the case of Hydrogen injection in single-strut
scramjet engine. The effect of this injection technique in mixing and
flame-holding is demonstrated. The results show good agreement with
the previous numerical and experimental investigations. And, the numerical
simulator proves its accuracy and robustness. |
