Combustion characteristic and aging behavior of bimetal thermite powders

چکیده
Nanothermites have been employed as fuel additives in energetic formulations due to their higher energy density over CHNO energetics. Nevertheless, sintering and degradation of nanoparticles significantly limit the practical use nanothermites. In this work, combustion characteristic aging behavior aluminum/iron oxide (Al/Fe2O3) nanothermite mixtures were investigated presence micron-scale nickel aimed produce bimetal thermite powders. The results showed that alumina content residue increased from 88.3% for Al/Fe2O3 96.5% mixture containing 20 wt% nickel. Finer particle sizes obtained nickel, indicative reduced agglomeration. Both suggested a more complete Aging was also assessed by measuring heat before after process. reduction less severe compared significant decrease without indicating better resistance

Computational Modeling of Combustion Wave in Nanoscale Thermite Reaction
Nanoscale thermites such as the composite mixture of nano-sized aluminum and molybdenum trioxide powders possess several technical advantages such as much higher reaction rate and shorter ignition delay, when compared to the conventional energetic formulations made of micron-sized metal and oxidizer particles. In this study, the self-propagation of combustion wave in compacted pellets of nanosc...

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
15 صفحه اولPulse Combustion: The Importance of Characteristic Times
The response of a valved pulse combustor to changes in the relative timing between the resonant pressure wave and the instantaneous energy release rate has been examined. Experiments were designed to examine the pulse combustor's response to independent changes in the experimental conditions that resulted in nearly independent changes in the fluid dynamic species mixing time, the fluid dynamic ...
