متن کاملFlame spread along a fuel rod in the absence of gravity
An analysis is carried out of the steady spread of a flame with infinitely fast kinetics over a thermally thin solid rod in the absence of gravity. Due to the radial convergence on the solid surface of the heat flux heating and vaporizing the fuel, the spread rate is found to be higher than for a flame spreading over a slab, and the region of the gas around the flame which is affected by molecu...
متن کاملبوزدایی از fuel oil deodorization of fuel oil
مطالعات و بررسی های انجام گرفته نشان می دهد ترکیبات بودار موجود در fuel oil عمدتا ترکیبات سولفوردار سخت مثل تیوفن، دی متیل بنزوتیوفن و ... بوده و روشهای بوزدایی همچون استخراج با حلالهای اسیدی و بازی ، رقیق کاری با گازولین ، ماسکینگ با بوتیل استات نتایج چندان مطلوبی در بوزدایی از آن نشان نمی دهند.همچنین روش جذب سطحی برای بوزدایی fuel oil تنها با استفاده از جاذب هایی همچون بنتونیت و توفیت...
15 صفحه اولEffect of Gap Height on Thin Fuel Opposed Flow Flame Spread in the Narrow Channel Apparatus
The Narrow Channel Apparatus (NCA) is designed to establish a fully developed laminar flow profile above and below a thin, flat, solid fuel or on one side of a thick fuel for flame spread investigations. Due in part to its ability to suppress buoyantly-induced flow, the NCA is under investigation as a possible test method for screening materials for space flight applications. This study focused...
متن کاملFlame Spread along Free Edges of Thermally Thin Samples in Microgravity
The effects of imposed flow velocity on flame spread along open edges of a thermally thin cellulosic sample in microgravity were studied experimentally and theoretically. In this study, the sample was ignited locally at the middle of the 4 cm wide sample, and subsequent flame spread reached both open edges of the sample along the direction of the flow. The following flame behaviors were observe...
