get_aerodynamic_mobility¶

Show source in aerodynamic_mobility_module.py:13

Calculate the aerodynamic mobility of a particle using classical fluid mechanics.

The aerodynamic mobility (B) can be determined by:

B = C / (6πμr)
- B is the aerodynamic mobility (m²/s).
- C is the slip correction factor (dimensionless).
- μ is the dynamic viscosity of the fluid (Pa·s).
- r is the radius of the particle (m).

Arguments¶

particle_radius : The radius of the particle in meters.
slip_correction_factor : Slip correction factor (dimensionless).
dynamic_viscosity : Dynamic viscosity of the fluid in Pa·s.

Returns¶

The particle aerodynamic mobility in m²/s.

Examples¶

Example

import particula as par
par.particles.get_particle_aerodynamic_mobility(
    particle_radius=0.00005,
    slip_correction_factor=1.1,
    dynamic_viscosity=0.0000181
)
