Diffusion in supersonic, turbulent, compressible flows
Physical Review E, 2003 We investigate diffusion in supersonic, turbulent, compressible flows. Supersonic turbulence can be characterized as network of interacting shocks.

Influence of injection angles on flow structures and mixing properties in a supersonic combustor at low Mach supersonic crossflow [PDF]
Scientific ReportsThe fuel-air mixing is of paramount importance in hypersonic air-breathing vehicles, and its performance is closely related to the fuel injection angle.

Shock Wave Capturing Numerically in Two Dimensional Supersonic Wind Tunnel for Different Configuration [PDF]
Engineering and Technology Journal, 2012 Numerical solutions of two dimensional Euler equations are obtained for transonic and supersonic flows. The shock capturing method is employed to solve compressible Euler equations by using MacCormack's time marching method that an explicit finite ...

Subsonic to Supersonic Nozzle Flows [PDF]
SIAM Journal on Applied Mathematics, 2013 Steady, irrotational flow of a compressible fluid through a two-dimensional planar and axisymmetric nozzle is formulated and solved numerically in the hodograph or velocity plane. The Legendre potential is used to express the governing equation which for planar flow is linear and for axisymmetric flow nonlinear.

International Journal of Aerospace Engineering, 2020 Boundary layer transition is a hot research topic in fluid mechanics and aerospace engineering. In low-speed flows, two-dimensional Tollmien-Schlichting (T-S) waves always dominate the flow instability, which has been modeled by Coder and Maughmer from ...

Numerical Studies of Particle-Gas Two-Phase Flowing through Microshock Tubes
Shock and Vibration, 2021 Microshock tubes are always used to induce shock waves and supersonic flows in aerospace and medical engineering fields. A needle-free drug delivery device including a microshock tube and an expanded nozzle is used for delivering solid drug powders ...

AIP Advances, 2021 Based on the kinetic theory, a three-dimensional multiple-relaxation-time discrete Boltzmann model (DBM) is proposed for nonequilibrium compressible reactive flows where both the Prandtl number and specific heat ratio are freely adjustable.

Approximate Analytical Models of Shock-Wave Structure at Steady Mach Reflection
Fluids, 2021 In this study, we obtain the comparative analysis of methods of quick approximate analytical prediction of Mach shock height in planar steady supersonic flows (for example, in supersonic jet flow and in narrowing channel between two wedges), that are ...
