متن کاملMeasurement of Combustion Temperature of Solid Propellant by FTIR Spectrometer
The temperature of solid state propellant combustion flame is studied by a Bruker OPAG33 Fourier Transform Infrared Spectrometer (FTIR). The infrared emission spectra of Nitrate Ester Plasticized Polyether Propellant (NEPE) solid propellant are measured with a resolution of 4 cm−1 at a testing distance of 20 m in real time. The temperature of NEPE propellant plume is calculated by using the fin...
متن کاملRole of Heterogeneous Reactions in Solid Propellant Combustion
steep temperature gradient is established in the solid This gradient extends to a depth of several microns, depending upon the external heat-flux rate As the propellant surface layers approach 150°C, the intermosaic blocks of the oxidizer particles decompose, and gaseous products diffuse to the oxidizer particle-fuel interface From ammonium perchlorate decomposition studies, the over-all reacti...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Unsteady Flow Evolution and Combustion Dynamics of Homogeneous Solid Propellant in a Rocket Motor
A time-resolved numerical analysis of combustion dynamics of double-base homogenous solid propellant in a rocket motor is performed by means of a Large-Eddy Simulation (LES) technique. The physiochemical processes occurring in the flame zone and their influence on the unsteady flow evolution in the chamber are investigated in depth. A five-step reduced reaction mechanism is used to obtain the t...
