In this paper the characteristics of unsteady three-dimensional incompressible flows with heat transfer are obtained along with artificial compressibility of Chorin. At first, compatibility equations and pseudo characteristics for three-dimensional flows are derived from five governing equations (continuity equation, Momentum equations in three directions, and energy equation) and then results ...
Hassan Abad Au-Sb prospect area is located in north of Khorasan Razavi Province about 45 km souht of Neyshabour. Volcanic rocks (rhyolite, rhyodacite, trachyandesite and andesitic-basalt) and sub-volcanic intrusive (Eocene-Oligocene) such as biotite diorite porphyry, biotite hornblende diorite porphyry, hornblende monzonite porphyry, biotite micogranite, micogranodiorite, and granodiorite were ...
purpose: to evaluate the influence of different confounding factors on the effect of intravitreal triamcinolone acetonide injection for refractory diabetic macular edema. methods: in a prospective placebo-controlled randomized clinical trial, 88 eyes with refractory diabetic macular edema were randomly assigned into two groups including 45 in the treatment group (4 mg intravitreal triamcinolone...
TC17 titanium alloy is widely used in the aerospace industry, but its combustion behavior and microstructure after are rarely investigated. Herein, ignition critical oxygen pressure, velocity, of were investigated by promoted tests under an oxygen-enriched environment. The results indicated that there three stages, ignition, splash, flame propagation, for process alloy. As compared to TC11 allo...
Image logs of 13 wells in the Rag Sefid Anticline show two systems of fractures developed under two deformation phase in the Dezful Embayment. This deformation phases are folding resulted from Zagros NE contraction and reactivation of the basement fault rotated the fold axial trace within the Hendijan-Izeh fault zone. Folding phase comprises four sets of fractures, which include axial and cross...
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
At this article we will study the Effect of Particle Radius on the Co-Flow Premixed Flame of Organic Particle Cloud. This analytical research frame work is thermal-diffusion model with assumption that the lewis number is unit. The structure of the flame is presumed to consist of three zone: a preheat vaporization zone where the rate of the gas-phase chemical reaction is small, a reaction zone ...
the aim of this study was to develop a microemulsion system as a medium for laccase-catalyzed reactions. phase behavior studies were conducted by constructing partial pseudo-ternary phase diagrams for systems comprising of cetyltrimethylammonium bromide (ctab), various organic solvents as the oil phase (i.e., hexane, cyclohexane, heptane, octane, isooctane, toluene, isopropyl myristate), two co...
In this paper we examine a mathematical model of solidification the melt in two-phase zone during formation forgings through liquid stamping. From simultaneous solution Fourier equations thermal conductivity for melt, zone, and solid crust, kinetics has been established effect external pressure on temperature fields components time hollow thin-walled thoroughly assessed.
