RISThermodynamic Properties of Pure and Mixed Thermal Plasmas Over a Wide Range of Temperature and Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Chemical composition and thermodynamics properties of different thermal plasmas are calculated in a wide range of temperatures (300–100,000 K) and pressures (10−6–100 atm). The calculation is performed in dissociation and ...
Study of the Constraint Selection Through ASVDADD Method for Rate-Controlled Constrained-Equilibrium Modeling on Ethanol Oxidation Without PLOG Reactions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Reduction of the detail chemical kinetic mechanism is important in solving complex combustion simulation. In this work, a model reduction scheme rate-controlled constrained-equilibrium (RCCE) is considered in predicting ...
Understanding the Effect of Capacitive Discharge Ignition on Plasma Formation and Flame Propagation of Air–Propane Mixture
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work is an experimental and computational study to investigate the effect of capacitive discharge ignition (CDI) on plasma kernel formation and flame propagation of air–propane mixture. This paper is mainly focused ...
Flame Stability in Inverse Coaxial Injector Using Repetitive Nanosecond Pulsed Plasma
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently, methane has been investigated as a feasible fuel for propulsion systems. The higher boiling point and higher density of methane, compared with hydrogen, makes its storage tank lighter, cheaper, and smaller to ...
Electrode Design for Thermal and Nonthermal Plasma Discharge Inside a Constant Volume Combustion Chamber
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Previous methods of achieving ignition in the Plasma, Combustion and Fluid imaging (PCFi) Laboratory’s Constant Volume Combustion Chamber (CVCC) utilizes either a standard or modified spark plug. The standard spark plug ...
