Chemical Meaning of Octane Number Analyzed by Topological Indices*

Correlation of the octane number (ON) of heptane and octane isomers with various topological indices, Z, w, p, and B, was studied. For single parameter correlation the index B by Balaban and w by Wiener show good results, whereas for two-parameter correlation almost any combination among the above four indices was found to give relatively high r value. Further, by adding the third parameter the...

Flame Dynamics in Supercritical Condition

Combustion under high-pressure conditions holds the potential for improved thermodynamic efficiency, enhanced power generation, and reduced emission of some pollutants. It underlies the technology of internal combustion engines such as the automotive engine, the gas turbine, and the rocket engine, for which the operating pressure can reach as high as 100s atm. At such high-pressure conditions, ...

Molecular Dynamics Method in Microscale Heat Transfer

Microscale swimming: the molecular dynamics approach.

The self-propelled motion of microscopic bodies immersed in a fluid medium is studied using molecular dynamics simulation. The advantage of the atomistic approach is that the detailed level of description allows complete freedom in specifying the swimmer design and its coupling with the surrounding fluid. A series of two-dimensional swimming bodies employing a variety of propulsion mechanisms-m...
