Collection Efficiency of Dry Cloth-Filters with Dust Loading

Collection Efficiency for Filters with Staggered Parallel Y and Triple Y Fibers: A Numerical Study

A numerical study is performed to determine the collection efficiency of filters composed of staggered parallel Y and triple Y fibers. By employing the Lattice Boltzmann method, the Navier–Stokes equations are solved for flow fields in a twodimensional domain with periodic boundary conditions. Trajectories of particles with different diameters arranging from 0.02 μm to 5 μm are then computed by...

Efficiency and Pressure Drop Effects of High Concentrations of Cement Dust on N95 Electret Filters

ield tests were conducted to measure the effects of high concentrations of cement dust on the penetration and pressure drop of N95 electret respirator filters from two manufacturers. Three groups of each manufacturer’s filter were tested: 1) untreated; 2) irradiated with ionizing radiation; 3) dipped in isopropanol for 15 seconds. The purpose of the irradiation and isopropanol treatments was to...

efficiency assessment of bag filters for removal of dust and heavy metals from emissions of electric arc furnaces

industrial processes release a range of gaseous and particulate pollutants containing heavy metals into the air. lack of enough attention to the design, installation, repair and maintenance of gas and dust filtration systems in industries, is one of reasons of increasing the emissions of these pollutants. hereon, the steel making processes is one of emission sources of heavy metals. according t...

Comparing Efficiency of Integration Methods for Cloth Simulation

Any cloth simulation system needs efficient numerical methods for integrating the equations that describe the mechanical behavior of the discrete representation of the cloth. Choosing the adequate method should be done with full knowledge of the advantages and weaknesses of the main techniques. This paper presents a quantitative comparison of the efficiency of the most common integration techni...
