NUMERICAL MODELLING OF HyShot II

Iso-surface of pressure at 180 kPa, coloured by the Mach number;

H2O distribution: on bottom slice

Transversal, 90° H2 injection into the incoming airstream generates very complex flow structures.

Vorticity generated in this way may be understood better by looking at the Crocco-Vazsonyi equation:

Isosurface of H2 at 0.01 mass fraction; color maps OH

Isosurface of H2 at 0.01 mass fraction colored by H2O

Temperature distribution at X=0.028 m ; H2 distribution on bottom slice

Isosurface of H2 at 0.01 mass fraction; color maps Temperature

NUMERICAL MODELLING OF HIFiRE 2

The research focuses on the understanding of the start-unstart nature of the scramjet by simulating cold flow, cold flow with injection and hot flow.
The Numerical simulations were carried out using RANS AND LES codes within the commercially avaible codes to Investigate the effect of different geometries, length, fuel injection angles that could help in understanding how to improve the design of scramjet engines.
The research aims to improve the combustion efficiency by decrease pressure losses.
Understanding of the combustion mechanism and improving chemistry of combustion by implementing new reaction mechanisms.
Aims to better understand the flow behaviour and vorticity nature.

NUMERICAL MODELLING OF EXPERIMENTAL TEST CASE
