water jet deflected by air

A water jet is deflected by moving air. In general, 2 phases are set up for water and air, which are then coupled as follows. Water to air via flow through porous medium

DarcyConstant($Air$) = [ min( 1, projY(2,%ind_kob%) )*1.0e5 ] DarcyBasisVelocity($Air$) = ( [projY(2,%ind_v(1)%)], [projY(2,%ind_v(2)%)], [projY(2,%ind_v(3)%)] )

Air to water via pressure boundary condition at free surface:

BC_p(0) = (%BND_free_implicit%, [equn($WaterInBox$)*(projY(1,%ind_p%)+projY(1,%ind_p_dyn%))])

Note: This is a completely different coupling approach from the one using BCON_CNTCT.
