    Hi everyone,

    I am currently working on wind-blown sand two-phase flow using OpenLB, but so far I can only modify the size and density of the particles. How can I apply an electric charge to the particles?

    I really appreciate any help you can provide.

    Are you using an Euler or Lagrange approach to model the particles?

    In order for to receive help we need to now more about the specifics of your setup – what you wrote till now only allows for vague guesswork.

    E.g. what model are you currently using for the particles? How specifically are you applying this model in OpenLB? How do you want to model the electric charge? Does the model support inter-particle interactions? Is there literature you reference? …

    Thank you mathias,I am using an Euler-Euler model to simulate particles, but I didn’t find a variable in that model where I can apply the charge density.

    Thank you Adrian,I am using the Euler-Euler model for my particles, which is based on the bifurcation3d case to add it to the channel3d. Currently, I am referring to the work of MM Rahman , trying to introduce an electrostatic force term into the particle control equation. I wonder if this is feasible? If it is feasible, what should I do next?

    I really appreciate any help you can provide.

    Helping for implementing a new model is beyond the scope of the forum. In the advanced section of the spring school we offer little suppert. Please, also consider for support or colaborations https://www.openlb.net/consortium/ .
