Comparison between modelled and analytical particle scale height as a function of particle size, for a turbulence strength of α = 10^-2. The black full line denotes modelled values and the red dotted line analytical values. Small particles R ≲ 10^-3 are perfectly coupled to the gas, whereas larger particles sediment towards the midplane. The slope change at R ≈ 0.5 is caused by the change from Epstein to Stokes drag regime. The particle size is given in units of R₁, where R₁ ≈ 1 m at r = 3 AU. Overall, modelled and analytical values are in good agreement.
