An extensive experimental and modeling study of 1-butene oxidation
In this study, a series of ignition delay time (IDT) experiments of 1-butene were performed in a high-pressure shock tube (HPST) and in a rapid compression machine (RCM) under conditions of relevance to practical combustors. ...
Quantitative geometric description of fracture systems in an andesite lava flow using terrestrial laser scanner data
Permeability hosted in andesitic lava flows is dominantly controlled by fracture systems, with geometries that are often poorly constrained. This paper explores the fracture system geometry of an andesitic lava flow formed ...
Influence of stormflow and baseflow phosphorus pressures on stream ecology in agricultural catchments
Stormflow and baseflow phosphorus (P) concentrations and loads in rivers may exert different ecological pressures during different seasons. These pressures and subsequent impacts are important to disentangle in order to ...
On the table of marks of a direct product of finite groups
We present a method for computing the table of marks of a direct product of finite groups. In contrast to the character table of a direct product of two finite groups, its table of marks is not simply the Kronecker product ...
Vertex algebras according to Isaac Newton
(IOP Publishing, 2017-09-08)
We give an introduction to vertex algebras using elementary forward difference methods originally due to Isaac Newton.
Zhu reduction for Jacobi n-point functions and applications
We establish precise Zhu reduction formulas for Jacobi n-point functions which show the absence of any possible poles arising in these formulas. We then exploit this to produce results concerning the structure of strongly ...
Pyrolysis of n-pentane, n-hexane and n-heptane in a single pulse shock tube
The pyrolysis of n-pentane, n-hexane and n-heptane have been studied behind reflected shock waves at pressures of 1.0-2.5 atm and at temperatures of 1000-1500 K. A single-pulse shock tube (SPST) was used to measure reactant, ...
Theoretical kinetics analysis for Ḣ atom addition to 1,3-Butadiene and related reactions on the Ċ4H7 potential energy surface
(American Chemical Society, 2017-09-08)
The oxidation chemistry of the simplest conjugated hydrocarbon, 1,3-butadiene, can provide a first step in understanding the role of polyunsaturated hydrocarbons in combustion and, in particular, an understanding of their ...
Autoignition characteristics of oxygenated gasolines
Gasoline anti-knock quality, defined by the research and motor octane numbers (RON and MON), is important for increasing spark ignition (SI) engine efficiency. Gasoline knock resistance can be increased using a number of ...
CO and H2O time-histories in shock-heated blends of methane and ethane for assessment of a chemical kinetics model
(ASME The American Society of Mechanical Engineers, 2017-09-13)
Methane and ethane are the two main components of natural gas and typically constitute more than 95% of it. In this study, a mixture of 90% CH4/10% C2H6 diluted in 99% Ar was studied at fuel lean (equiv. ratio = 0.5) ...
