On Velocity Feedback Combustion Oscillation

open access: yesTransactions of the Japan Society of Mechanical Engineers, 1963
Low frequency oscillation encountered in combustion system involving entrance resistance, exit resistance and capacity, was studied experimentally as well as theoretically and its nature was clarified. Various factors influencing on the frequency and the amplitude of oscillation, for example, entrance and exit resistance, capacity, shape of burner and ...

Experimental Investigation on Knock Characteristics from Pre-Chamber Gas Engine Fueled by Hydrogen

open access: yesEnergies
Hydrogen-fueled engines require large values of the excess air ratio in order to achieve high thermal efficiency. A low value of this coefficient promotes knocking combustion.

Chaotic Combustion in Spark Ignition Engines

open access: yes, 2002
We analyse the combustion process in a spark ignition engine using the experimental data of an internal pressure during the combustion process and show that the system can be driven to chaotic behaviour.

Experimental Study of Combustion Fluctuation Reduction Using In-Cylinder Pressure Estimation in Gasoline Engine

open access: yesJIRAE (International Journal of Industrial Research and Applied Engineering), 2018
Gasoline engines needs to reduce its negative emission waste and raise its thermal efficiency. Previous studies have shown an improvement of engines by regulating the ignition timing and retaining the engine at certain air-to-fuel ratio.

Characterization and modeling of aperiodic pressure oscillations in combustion chambers [PDF]

open access: yes, 1991
Classification of the long-term dynamical behavior of pressure oscillations in a laboratory combustion chamber has been performed using methods of modern dynamical systems theory. The method involves the construction of a phase-space representation

Applications of Various Methods of Analysis to Combustion Instabilities in Solid Propellant Rockets [PDF]

open access: yes, 1996
Instabilities of motions in a combustion chamber are consequences of the coupled dynamics of combustion processes and of the flow in the chamber. The extreme complexities of the problem always require approximations of various sorts to make progress in

Analysis of the forces driving the oscillations in 3D fluidic oscillators [PDF]

open access: yes, 2019
One of the main advantages of fluidic oscillators is that they do not have moving parts, which brings high reliability whenever being used in real applications.
