“…Contact potential di erence measurement is a standard tool to quantify electron transfer when two matters are brought into contact (Itakura et al, 1996). In the present study perturbations in the permittivity values due to the charge accumulation with time are measured and compared with surface potential readings and respective contact potential di erence measurements.…”

“…In addition to these contributions to charge transfer, Itakura et al 40 found that electrostatic leakage from the particle electric field to its surroundings, after the particles are no longer in contact, plays a significant role in the final charge of the particle. This effect is directly proportional to i.e.…”

When particles are transported in pipelines, they acquire electrostatic charges as they come into contact with the pipe wall. Charged particles can cause problems such as particle agglomeration, blockage, and explosion. Understanding the particle charge can help to prevent these issues. This study investigates a technique for predicting the particle charge in a straight pipe of any given length, as well as the pipe length at which electrostatic equilibrium occurs, through experimentation in a short 1m pipe section.Experimentation with five different types of particles and four pipe wall materials at longer pipe lengths were used to validate the technique. This predictive technique is applicable to a range of particle shapes and sizes under the restriction that charge transfer is due to impact charging. Heading:Particle technology and fluidization

“…Until now, majority of the work was involved in developing the understanding on the tribo-charging mechanism [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49]. Several studies were also carried out to know the tribocharging characteristics in pneumatic conveying [50][51][52][53][54][55][56][57][58][59][60][61][62][63] and gassolid fluidized bed system [64][65][66][67].…”
