Vapor-phase Oxidation and Spontaneous Ignition - Correlation and Effect of Variables


Book Description

The spontaneous ignition temperatures of eight structurally different hydrocarbons were determined and correlated with the behavior of the same hydrocarbons toward vapor-phase oxidation. Since good correlation of the two phenomena was obtained, it is likely that similar oxidative mechanisms are operative in both.




The Gas-Phase Oxidation of Hydrocarbons


Book Description

The Gas-Phase Oxidation of Hydrocarbons reviews research on the mechanism of oxidation of paraffins, naphthenes, olefines, and aromatic hydrocarbons and explains in detail the phenomena and theories with significant kinetic equations and graphs. This book first presents a study of the development of research on the gaseous-phase oxidation of hydrocarbons. The non-chain schemes for the oxidation of hydrocarbons, such as hydroxylation, peroxidation, and aldehyde and dehydrogenation schemes, are then discussed. This book also presents experimental investigations and important topics such as oxidation of methane and olefinic hydrocarbons. This selection will be invaluable to students and experts in the field of chemistry and related disciplines.

Effect of Pneumatic De-icers and Ice Formations on Aerodynamic Characteristics of an Airfoil


Book Description

Measurements of lift, drag, and pitching moment of an NACA 0011 airfoil were made in icing using two types of pneumatic de-icers, one having spanwise inflatable tubes and the other having chordwise tubes. Ice remaining after inflation of the spanwise-tube de-icer increased airfoil section drag 7 to 37 percent for 0 to 4.6 degrees angle of attack over the ranges of airspeed, total air temperature, liquid-water content, and cycle times covered. This drag increase became constant after a few de-icing cycles. Drag increases due to ice remaining on the chordwise-tube de-icer were similar to those for the spanwise-tube de-icer. Minimum airfoil drag in icing (averaged over a de-icing cycle) was usually obtained with a short (about i min) de-icing cycle.
