Initial Collection Efficiency of Dry Cloth Filter

Initial Collection Efficiency of Electret Filter and Its Durability for Solid and Liquid Particles t

Expressions to describe the initial collection efficiency of electret filters for both charged and neutral particles were derived covering a wide range of Coulombic force and induced force parameters including the interceptional effect. The prediction equations were in good agreement with the experimental data. Further, the electret charge stability in humid air and in exposure to liquid and so...

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...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Modeling Filter Bypass: Impact on Filter Efficiency

Current models and test methods for determining filter efficiency ignore filter bypass, the air that circumvents filter media because of gaps around the filter or filter housing. In this paper, we develop a general model to estimate the size-resolved particle removal efficiency, including bypass, of HVAC filters. The model applies the measured pressure drop of the filter to determine the airflo...
