Design and performance evaluation of a high temperature axisymmetric plug nozzle [PDF]

open access: yesINCAS Bulletin, 2023
In this study, a method for designing supersonic nozzles with axisymmetric plugs at high temperature has been proposed. The approach is based on the theory of Prandtl-Mayer expansion at high temperatures using the method of characteristics.

Thrust Vectoring of a Fixed Axisymmetric Supersonic Nozzle Using the Shock-Vector Control Method

open access: yesFluids, 2021
The application of the Shock Vector Control (SVC) approach to an axysimmetric supersonic nozzle is studied numerically. SVC is a Fluidic Thrust Vectoring (FTV) strategy that is applied to fixed nozzles in order to realize jet-vectoring effects normally ...

Numerical Simulation of Low Reynolds Number Particle-Laden Gas Jet by Vortex Method

open access: yesJournal 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.

The thermochemical non-equilibrium scale effects of the high enthalpy nozzle

open access: yesAdvances 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 ...
