This paper tends to investigate the performance of a separator cyclone used in cement industries in Iran. This investigation was performed using CFD modeling, which is validated by other valid studies. Separator cyclone performance includes of two important parameters as pressure drop and collection ratio. In this presented study, the pressure drop has been considered to assess the performance ...

  Background and aims: Extensive industrial and production activities are one of the major sources of dust. In many cases, cyclones are used as the control measure. The removal efficiency of dust in cyclones depends on different factors. Some of these factors are, the design parameters, e.g. cyclone diameter, particle density, operating temperature and fluid physical properties, density of gas ...

BACKGROUND The traditional cyclone has been developed for the removal of airborne silica particles from local exhaust ventilation (LEV). The objective of this research was to evaluate the effects of velocity and particles load on efficiency of cyclone in the Stone Crushing Units at Azendarian Area. METHODS After the designing and installing the traditional cyclone, downstream and upstream sam...

The goal of this study was to simulate the Gonu cyclone and its resulting waves in the Gulf of Oman. The Gonu cyclone wind field was simulated using CGW module of Mike 21 and cyclone track data. Then, using SW module of Mike 21, the simulated wind field and ECMWF parametric boundary condition, the resulting wave field was simulated. The maximum significant wave height of 10.5 m in the Gulf of O...

UNLABELLED Cyclone aims at facilitating the use of BioCyc, a collection of Pathway/Genome Databases (PGDBs). Cyclone provides a fully extensible Java Object API to analyze and visualize these data. Cyclone can read and write PGDBs, and can write its own data in the CycloneML format. This format is automatically generated from the BioCyc ontology by Cyclone itself, ensuring continued compatibili...

A new theoretical method for computing travel distance, number of turns, and cyclone pressure drop has been developed and is presented in this article. The flow pattern and cyclone dimensions determine the travel distance in a cyclone. The effective number of turns was calculated based on the travel distance. Cyclone pressure drop is composed of five pressure loss components. The frictional pre...

To assess the impact on health of the cyclone and tidal wave that struck the southern coast of Bangladesh on the evening of 29 April 1991, a team of health professionals visited cyclone affected areas from 4-27 June, 1991. Team members met with health workers and officials of the Government of Bangladesh and with staff pom nongovernmental organizations, and conducted field surveys in two severe...

The 30–60-day Madden–Julian oscillation (MJO) has been documented in previous research to impact tropical cyclone (TC) activity for various tropical cyclone basins around the globe. TheMJOmodulates largescale convective activity throughout the tropics, and concomitantly modulates other fields known to impact tropical cyclone activity such as vertical wind shear, midlevelmoisture, vertical motio...
