Design and Study of Swirl Injector of Pulse Detonation Engine [PDF]

, 2017
Future Indian Air force and Navy Capabilities indicate the need for a supersonic cruise missile. Therefore, there exists a need for a low cost, light-weight, and efficient means of supersonic propulsion. In this paper my main emphasis on Pulse Detonation

Research Progress on Rotating Detonations of Liquid Hydrocarbon Fuels [PDF]

Hangkong bingqi
Detonation waves propagate at velocities exceeding 1 000 m/s, enabling the reactants to complete reaction without significant expansion, thereby an isochoric combustion process can be achieved.

INITIATION OF ROTATING DETONATION IN EXPERIMENTAL COMBUSTION CHAMBER – PRACTICAL REALIZATION

Journal of KONES. Powertrain and Transport, 2015
Since 2009 in the Institute of Aviation, Warsaw a project that aim is to develop combustion chamber with rotating detonation for turbine engine has been carried out. Desired fuel is aviation kerosene (Jet-A) detonated in air. One of the most important problems to be solved was the initiation of rotating detonation in combustible mixture, which requires

Numerical and boundary condition effects on the prediction of detonation engine behavior using detailed numerical simulations

Frontiers in Aerospace Engineering, 2023
High-fidelity numerical simulations of an experimental rotating detonation engine with discrete fuel/air injection were conducted. A series of configurations with different feed-plenum pressures but with constant equivalence ratio were studied.

Kinetic modeling of detonation and effects of negative temperature coefficient

, 2016
The kinetic modeling and simulation of reactive flows, especially for those with detonation, are further investigated. From the theoretical side, a new set of hydrodynamic equations are deduced, where the viscous stress tensor and heat flux are replaced ...

Towards an understanding of Type Ia supernovae from a synthesis of theory and observations

, 2013
Motivated by the fact that calibrated light curves of Type Ia supernovae (SNe Ia) have become a major tool to determine the expansion history of the Universe, considerable attention has been given to, both, observations and models of these events over ...

Ion Sensors for Pulsed and Continuous Detonation Combustors

Chemosensors, 2023
Presented in the article are the design and operation principles of ion sensors intended for detecting the propagating reaction fronts, the deflagration/detonation mode, apparent subsonic/supersonic propagation velocity of the reaction front, and ...

Application of introduced nano-diamonds for the study of carbon condensation during detonation of high explosives

, 2008
This paper describes the experimental studies of the formation of nano-diamonds during detonation of TNT/RDX 50/50 mixture with small-angle x-ray scattering (SAXS) method at a synchrotron radiation beam on VEPP-3 accelerator.

Reactant Jetting in Unstable Detonation [PDF]

, 2009
We note the common existence of a supersonic jet structure locally embedded within a surrounding transonic flow field in the hitherto unrelated phenomena of unstable gaseous detonation and hypervelocity blunt body shock wave interaction. Extending prior
