Research on experiment and simulation of charged spherical metal particle collision characteristic under DC electric field

Metal particle movement and distribution characteristics under AC voltage and ball‐plane electrodes

“…When leaving the electrode surface, particle is driven under alternating force; when particle collides with the electrode, the collision recovery coefficient λ c can be found by reference [22]:…”

“…The method was achieved by AC/DC Module in software COMSOL. Parameter setting of particle charging and collision referred to the reference [22] and (11) and (12). In this model, the collision recovery coefficient was 0.55.…”

“…In order to eliminate the metal particles in GIS, particle capture traps are usually designed in the production with the withstand voltage test before its operation, which enables particles to move to the trap [1][2][3][4][5][6][7][8][9]. In order to optimise particle traps and apply withstand tests, there are many researches on particle movement characteristics [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. In reference [10,12], a wedge of electrode structure was established after analysing the electric field among insulator, electrodes, and gas in GIS.…”

“…With the increased crash recovery coefficient, the motion amplitude increases. In reference [22], the crash recovery coefficients of aluminium, copper, and stainless steel particles obtained by test based on the method of ultrasonic are 0.55, 0.75, and 0.80, respectively.…”
