Stagnation Hugoniot Analysis for Steady Combustion Waves in Propulsion Systems [PDF]

open access: yes, 2006
The combustion mode in a steady-flow propulsion system has a strong influence on the overall efficiency of the system. To evaluate the relative merits of different modes, we propose that it is most appropriate to keep the upstream stagnation state fixed ...

Enthalpy of Combustion of Microcrystalline Cellulose

open access: yesJournal of Research of the National Bureau of Standards, 1981
A test substance with characteristics and properties similar to those of cellulose-based solid waste products is needed to calibrate calorimeters and combustors which will be routinely burning these materials to determine their calorific values precisely for use in commerce.
