Dynamics of cellular flame deformation after a head-on interaction with a shock wave: reactive Richtmyer-Meshkov instability
Hongxia Yang, Matei Ioan Radulescu
Shock flame interactions are fundamental problems in many combustion applications ranging from flame acceleration to flame control in supersonic propulsion applications. The presen…
Viscous jetting and Mach stem bifurcation in shock reflections: experiments and simulations
S. S. -M. Lau-Chapdelaine, Q. Xiao, M. I. Radulescu
Shock reflection experiments are performed to study the large-scale convective mixing created by the forward jetting phenomenon. Experiments are performed at a wedge angle of $θ_{\…
The Effect of the Polytropic Index γ on the Structure of Gaseous Detonations
Aliou Sow, S. SM. Lau-Chapdelaine, M. I. Radulescu
The present study aims to clarify the effect of the polytropic index (i.e., the ratio of specific heats in the context of a perfect gas) on the detonation structure. This is addres…
On the two separate decay time scales of a detonation wave modelled by the Burgers equation and their relation to its chaotic dynamics
S. SM. Lau-Chapdelaine, M. I. Radulescu
This study uses a simplified detonation model to investigate the behaviour of detonations with galloping-like pulsations. The reactive Burgers equation is used for the hydrodynamic…
On the shock change equations
Matei Ioan Radulescu
We revisit and derive the shock-change equations relating the dynamics of a shock wave with the partial derivatives describing the motion of a reactive fluid with general equation…
Compressible flow in a Noble-Abel Stiffened-Gas fluid
Matei Ioan Radulescu
While compressible flow theory has relied on the perfect gas model as its workhorse for the past century, compressible dynamics in dense gases, solids and liquids have relied on ma…
