In a recent paper<\/a> <\/strong><\/span>for the journal <\/span>Computational Particle Mechanics<\/span><\/i>, the author detailed the multiphysics and multiscale computational procedure <\/strong><\/span>used for enhancing high-fidelity simulation on electrostatically charged particles applied onto metal surfaces.<\/span><\/p>\n

Dr Gimenez's approach, which has been successfully validated <\/strong><\/span>in experimental settings, addresses the challenges posed by traditional models, which require “substantial computational effort” and have limited practical application.<\/span><\/p>\n

\"RVE<\/p>\n

RVE configuration for particle-laden flows. Dimensionless inputs characterize the carrier and particulate phase.<\/span><\/span><\/p>\n

The work studied the turbulent flow of charged particles<\/strong><\/span> using the multiscale pseudo-direct numerical simulation method (P-DNS), and simulated representative volume elements considering particle interaction with the surrounding gas and electrostatic field. The paper also presents a coat film model that quantifies thickness on the target surface.<\/span><\/p>\n

The author reinterpreted the input body forces of a reduced synthetic model from existing literature, adding <\/span>Coulomb forces<\/span><\/a> to achieve more accurate and efficient results <\/strong><\/span>at the coarse and global scale.<\/span><\/p>\n

When tested on complex geometry surfaces, Dr Gimenez’s model was able to accurately predict the behaviour of the electrostatic coating process<\/strong>,<\/span> demonstrating the methodology’s potential as a “rapid predictive tool” for coating spray technology.<\/strong><\/span><\/p>\n

According to the author, this methodology can further reduce the environmental impact of powder coating technology, lowering the footprint of energy-intensive sectors such as the automotive, building, and manufacturing industries.<\/strong><\/span><\/p>\n
