A finite element model was generated of a Søderberg electrode in a ferromanganese smelter. In this model, the casing and fins were modelled explicitly, and temperature-dependent material properties were included. A two-stage analysis procedure was used, the first part being a coupled thermal-electrical analysis using an applied DC current. As the casing material was non–magnetic, the DC current...

This paper deals with the design and performance analysis of centrifugal pump. In this paper, centrifugal pump is analyzed by using a single-stage end suction centrifugal pump. Two main components of a centrifugal pump are the impeller and the casing. The impeller is a rotating component and the casing is a stationary component. In centrifugal pump, water enters axially through the impeller eye...

Design and manufacturing technology of high pressure multistage pumps which are commonly utilized in oil and gas industries, used to be imported from foreign companies. Due to international sanctions against I. R. Iran, it started to be designed and launched domestically. Nowadays all production lines including design, manufacturing and testing of these pumps have been performed by Iranian expe...

A frequent challenge encountered in the exploitation of mature gas fields located Getic Depression is sand production. Causes production are mainly related to degree rock consolidation, lithology, increasing water and rates. The effects multiple such us low productivity wells, accumulation into surface equipment, erosion downhole plugging perforation zone casing damage. current paper will addre...

ABSTRACT The cultivation of button mushroom has reached a high technological level in developed countries and is associated with productivity indices. This involves not only compost production crop management but also the casing layer. Peat been established as one most appropriate materials for due to its excellent properties. However, good-quality peat available all countries, renewable, which...

This study was conducted to evaluate small-scale hot-water postpackaging pasteurization (PPP) as a postlethality (post-cooking) treatment for Listeria monocytogenes on ready-to-eat beef snack sticks and natural-casing wieners. Using a commercially available plastic packaging film specifically designed for PPP applications and 2.8 liters of boiling water (100 degrees C) in a sauce pan on a hot p...

Stress state analysis to casing-cement sheathformation system (CCSFS) is the foundation of the wellbore integrity design and examination. Many elastic mechanic models have been established to calculate the stresses and displacements of CCFS, but all analytical models and most finite element models took no account of the initial loaded state, and ignored the initial stresses and displacements on...

Well "X-01" is a slant (J-Type) directional well and will be subjected to appropriate technically qualified drilling casing planning in order prevent problems such as burst, collapse, tension that can cause increased internal external pressure loads experienced by the casing. The methodology used this research document study quantitative analysis using Drilling Software taking into account load...

The aim of this study was to analyze yields, biological efficiency, earliness (expressed as days to first harvest), and precociousness and establish models for the mushroom growing according to these parameters. The experiment followed a double factorial design with four sources of calcium (calcitic limestone, calcitic limestone + gypsum, dolomitic limestone and dolomitic limestone + gypsum) an...
