Effect of Induced Charge on Deposition of Uniformly Charged Particles in a Pediatric Oral-Extrathoracic Airway

Figures & data

FIG. 1 Schematic of the setup to investigate the effect of particle electrostatic charge, aerodynamic diameter, and flow condition on deposition in a pediatric oral-extrathoracic airway, after Azhdarzadeh et al. (2014).

FIG. 2 Comparison of the data from the present setup for the deposition of neutralized particles in the idealized child mouth-throat with the results reported by Golshahi et al. (2013).

FIG. 3 Effect of charge on deposition of particles in the idealized child oral-extrathoracic airway at two flow rates: (a) Q = 10 and 20 L/min for d _a = 3.58 μm, (b) Q = 10 and 20 L/min for d _a = 4.43 μm, and (c) Q = 10 and 20 L/min for d _a = 5.88 μm.

FIG. 4 Deposition in an idealized pediatric oral-extrathoracic airway including inertial and induced charge effects along with suggested dimensionless Equation (8) (a) and Equation (10) (b).
