particle_diffusion_coefficient¶
Show source in diffusion_coefficient.py:21
Calculate the diffusion coefficient of a particle.
Arguments¶
temperature
- The temperature at which the particle is diffusing, in Kelvin. Defaults to 298.15 K.boltzmann_constant
- The Boltzmann constant. Defaults to the standard value of 1.380649 x 10^-23 J/K.aerodynamic_mobility
- The aerodynamic mobility of the particle [m^2/s].
Returns¶
The diffusion coefficient of the particle [m^2/s].
