Numerical simulation of a vectored axisymmetric nozzle
AIP Conference Proceedings, 2020 A CFD based approach to the fully three-dimensional simulation of vectored nozzle is presented. The underlying tech- nology used is based on an active flow control technique known as Fluidic Thrust-Vectoring. The flow governing equations are solved by using a finite volume discretization of the compressible Unsteady RANS equations.

Numerical Simulation of Low Reynolds Number Particle-Laden Gas Jet by Vortex Method
Journal of Fluid Science and Technology, 2009 An air jet, which remains laminar and axisymmetric in the single-phase flow condition, is simulated numerically in the particle-laden condition. The vortex method for particle-laden gas jet proposed by the authors is employed for the simulation.

Lift-up, Kelvin-Helmholtz and Orr mechanisms in turbulent jets [PDF]
, 2020 Three amplification mechanisms present in turbulent jets, namely lift-up, Kelvin–Helmholtz and Orr, are characterized via global resolvent analysis and spectral proper orthogonal decomposition (SPOD) over a range of Mach numbers.

The thermochemical non-equilibrium scale effects of the high enthalpy nozzle
Advances in Aerodynamics, 2020 The high enthalpy nozzle converts the high enthalpy stagnation gas into the hypervelocity free flow. The flow region of the high enthalpy nozzle consists of three parts: an equilibrium region upstream of the throat, a non-equilibrium region near the ...
