Computing the near-wall region in gas micro- and nanofluidics: critical Knudsen layer phenomena

, 2006
In order to capture critical near-wall phenomena in gas micro- and nanoflows within conventional CFD codes, we present scaled Navier-Stokes-Fourier (NSF) constitutive relations.

Improvement of the turn-down ration of gas turbines by auto thermal on board syngas generation

Journal of the Global Power and Propulsion Society, 2017
The low reactivity of natural gas leads to a sudden increase of carbon monoxide (CO) and unburned hydrocarbons (UHC) emissions below a certain load level, which limits the part load operation range of current utility gas turbines in combined cycle power ...
