LPT random walk
 

I want to use Lagrangian particle and stochasitc trasport equation to simulate passive scalar tranportation. But I don't know how to incorporate effactive diffusivity from turbulece model to partciel. Can somebody help?
How can I let particel read turbulence->nuEff()?

I achieved it by creating a volScalarField nuEff in createField.H and then in the solver assign turbulence->nuEff() to the nuEff field. In this way, the cloud can take the nuEff field as a member and then interpolate it to the particle location.
It seems to work, but is there a more elegant way of doing it ?

Hey,

it's been a while since your last post but I am working on the same issue at the moment.
Have you built a more "elegant" solution?

Cheers
