Several complicated physical processes are involved in an ESP, including the turbulent flow, the ionization of gas by corona discharge, particles' movement, and the displacement of electric charge. The attachment of ions charges suspended particles in the gas media. Then, charged particles in the fluid move towards the collection plate and stick on it. The numerical model comprises the gas flow, electrostatic field, and particle motions. The collection efficiency of the wire-plate type ESP is investigated for the particle diameter range of 0.02 to 10 mu m. It is observed that electric field strengths and current densities show considerable variation in the solution domain. Meanwhile, changing supply voltage and charging wire diameters significantly affect the acquired charges on the electrostatic field and particle collecting efficiencies. Simultaneously, the distance between the charging and collecting electrodes and the main fluid inlet velocity has an important effect on the particle collection efficiency. The influence of the different ESP working conditions and particle dimensions on the performance of ESP are investigated and discussed.eninfo:eu-repo/semantics/openAccessMoisture transportHeat-transferAir-flowCoronaModelPerformancePredictionBehaviorsElectrostatic precipitatorsCollection efficiencyModellingCfdDpmScience & technologyPhysical sciencesTechnologyChemistry, multidisciplinaryEngineering, multidisciplinaryMaterials science, multidisciplinaryPhysics, appliedChemistryEngineeringMaterials sciencePhysicsArticle000824035000001121310.3390/app121364012076-3417
