بررسي پديده ناپايداري فاز در سوخت هاي fae ژله اي و پايدار سازي آن

Study of phase instability phenomena in gelled FAE fuels andtheir stabilization

با اضافه كردن ذرات جامد پرانرژي فلزي و غيرفلزي به مواد منفجره هوا سوخت (fae)سطح انرژي و در نتيجه كارايي آنها به ميزان فوق العاده اي افزايش مي يابد. اهميت توزيع يكنواخت و همگن اين ذرات جامد درون سوخت مايع موجب شده كه مشخصه ي كلوييدي ژل ها و ژله اي نمودن اين نوع سوخت ها به عنوان يك مزيت مورد توجه قرار گيرد از طرف ديگر به دليل اختلافات وزني ذرات جامد با سوخت مايع معمولا پديده اي به نام ناپايداري فاز و ته نشين شدن ذرات جامد كه عمدتا ناشي از تاثير نيروهاي خارجي مي باشد.

The energy level and performance of fuel-air explosives (FAE) will be increase significantly with adding metal and non-metal energetic solid particles. Importance of homogeneous and uniform distribution of these solid particles into liquid fuel causes that the colloidal characteristic of gels and gelling of these kinds of fuels has been considered as an advantage. On the other hand, because of the difference between solid particles and liquid fuel specific gravity, phenomena that called phase separation and the settling of solid particles usually take place in these compounds that is mainly due to the outer forces effect such as gravitational force and weapon acceleration. In this paper, we introduce the fuel-air explosives and advantages of their gelling initially. Then we have described different parameters affected on phase stability in FAE gelled fuels with and without energetic solid particles such as particle size and amount of gelling agent, size and density of added solid particles and etc. However the stabilizing and phase stabilization methods have been studied for FAE gelled fuels.
