The primary moisture separator—a key component in the PWR nuclear power plant—determines quality of supplied steam to a turbine. Investigating its characteristics is important because supplying with excessive droplet entrainment results damages pipes, valves, and turbines plant circuits. In this numerical study, particle tracking method Eulerian–Lagrangian methodology used investigate separator...

Magnetic reconnection is a fundamental process in laboratory, magnetospheric, solar and astrophysical plasma, whereby magnetic energy converted into heat, bulk kinetic fast particle energy. Its nature two dimensions much better understood than three (3D), where its character completely different has many diverse aspects that are currently being explored. Here we focus on the magnetohydrodynamic...

Purpose. This research investigates the separation process performed by a magnetic separator. The is used to isolate ferrous materials from those which are not. Hence, prototype of dry separator designed. It should be said that this study defines effect different parameters (roll speed, force, and mass silica sand particle) on efficiency. Methodology. influence several such as centrifugal prope...

the aim of this study was to evaluate the physical characteristics, chemical composition and protein fractions of sugar beet pulp produced in iran and comparing them with the tabular values of cornell net carbohydrate and protein system. a total of 39 samples of 13 different sugar factories were sampled from iran-wide. particle size distributions of samples were determined using the penn state ...

We prove separator theorems in which the size of the separator is minimized with respect to non-negative vertex costs. We show that for any planar graph G there exists a vertex separator of total vertex cost at most c q P v2V (G) (cost(v)) 2 and that this bound is optimal within a constant factor. Moreover such a separator can be found in linear time. This theorem implies a variety of other sep...

We address the problem of nding a minimal separator in a di rected acyclic graph DAG namely nding a set Z of nodes that d separates a given pair of nodes such that no proper subset of Z d separates that pair We analyze several versions of this problem and o er polynomial algorithms for each These include nding a minimal separator from a restricted set of nodes nding a minimum cost separator and...

"Pre-separator plus1D2D cyclone" and "pre-separator plus 1D3D cyclone" systems were tested with ground gin trash, which contains 10.35% lint fiber and 5.49% fine dust (less than 100 μm). Test results indicate that the pre-separator collected gin trash at over 97% collection efficiency. There were no significant differences in emission concentrations and overall collection efficiencies from thes...
