Accounting for convective effects in zero-Mach-number thermoacoustic models [PDF]

, 2014
This paper presents a methodology to account for some mean-flow effects on thermo-acoustic instabilities when using the zero-Mach-number assumption. It is shown that when a computational domain is represented under the M=0 assumption, a nonzero-Mach ...

Enhancing properties of iron and manganese ores as oxygen carriers for chemical looping processes by dry impregnation [PDF]

, 2015
The use of naturally occurring ores as oxygen carriers in CLC processes is attractive because of their relative abundance and low cost. Unfortunately, they typically exhibit lower reactivity and lack the mechanical robustness required, when compared to ...

An Optimization-Based Approach for the Development of a Combustion Chamber for Residential Micro Gas-Turbine Applications

Chemical Engineering Transactions, 2015
In the field of micro gas turbine, attention must be paid on the design of the combustion chamber to reduce NOx formation without compromising combustion efficiency. To this goal flameless combustion represents an appealing solution.

Numerical analysis of transient combustion response to acoustic oscillations in axisymmetric rocket motors [PDF]

, 1998
A numerical analysis of unsteady motions in solid rocket motors with a nozzle has been conducted. The formulation treats the complete conservation equations for the gas phase and the one-dimensional equations in the radial direction for the condensed

Limits of steady burning propellants in the phenomenological theory using effective initial temperature

Journal of Thermal Science and Technology, 2015
A new form of the phenomenological theory of unsteady combustion of solid propellants is proposed. It is based on the explicit use of a single physical quantity - effective initial combustion temperature.
