Detailed Description

template<class CloudType>
class Foam::CoulombForce< CloudType >

Particle electric force model involving the Coulomb force calculation.

$\‍[ \vec{F}_\mathrm{E} = q \, \vec{E} \‍]$

where

$\vec{F}_\mathrm{E}$	=	Coulomb force [kg m s^{-2}]
	=	Electric charge of particle [A s]
$\vec{E}$	=	Electric field [kg m^2 A^{-1} s^{-3} m^{-1}]

Usage

Minimal example by using constant/cloudProperties:

subModels
{
    solution
    {
        interpolationSchemes
        {
            <Ename>     <interpolationScheme>;
        }
    }

    particleForces
    {
        Coulomb
        {
            q       <Function1<scalar>>;
            E       <word>;
        }
    }
}

where the entries mean:

Property	Description	Type	Reqd	Deflt
`type`	Type name: Coulomb	word	yes	-
`q`	Electric charge of particles	<Function1<scalar>	yes	-
`E`	Name of electric field	word	no	E

Note

Particle electric charge can be input as a function of particle diameter:

    particleForces
    {
        Coulomb
        {
            q   table
            (
                // d [m]           q [C = A s]
                (1e-06             -5.0e-11)
                (1e-05             -1.0e-10)
            );
            E   electricPotential:E;
        }
    }
