Member Function Documentation

add_load_to_obstacles()

template<int dim, typename number , typename ObstacleType >

void MeltPoolDG::StokesLawSphericalParticleForce< dim, number, ObstacleType >::add_load_to_obstacles

(

ObstacleField< dim, number, ObstacleType > &

obstacle_field

)

const

Computes the hydrodynamic force exerted by the fluid on all obstacles in the provided obstacle field. The force on each obstacle is evaluated using Stokes' law (valid for Re << 1!), based on the translational velocity of the particle at its center and the fluid velocity at the same location:

\[ \mathbf{F} = 6 \pi \mu R \left( \mathbf{u}_f - \mathbf{u}_p \right). \]

Parameters

obstacle_field

Reference to the obstacle field containing the obstacles for which the force will be computed.
