Oxidation of a Coal-to-Liquid Synthetic Jet Fuel ...

The oxidation of the CtL-fuel under these conditions was modeled using a detailed kinetic reaction mechanism consisting of 8217 reactions and 2185 species and a 4-component surrogate fuel mixture (n-decane, iso-octane, n-propylcyclohexane, and n-propylbenzene). A reasonable representation of the kinetics of oxidation of this FSJF was obtained.

Measurements of the Flow Distribution in Subchannels of …

The iso-kinetic sampling technique is widely known as a traditional measurement method for the flow rate of subchannels in a rod bundle. Lorenz and Ginsberg [4] used a 50.8 mm height bare rod arrayed flow divider on a wire wrapped rod bundle. A sampling device was inserted at a particular subchannel and the sampling flow was measured
