class ansys.cfx.core.generated.pre_processing.settings_261.drag_force_1.drag_force(name: str | None = None, parent=None)

Bases: Group

Specifies drag force between two phases.

Attributes

Attribute	Summary
option	The ‘Drag Force’ option.
drag_coefficient	‘Drag Coefficient’ parameter.
minimum_drag_coefficient	‘Minimum Drag Coefficient’ parameter.
volume_fraction_correction_exponent	Exponent for volume-fraction dependence of drag force. Omission of this parameter, or a unit exponent, are equivalent to no correction. Typical exponent values for dense concentrations are -1.65 for solids, 4 for bubbles.
linearisation_blend_factor	‘Linearisation Blend Factor’ parameter.
redistribute_in_rhie_chow	Indicates whether momentum source is redistributed.
drag_coefficient_1	‘DRAG COEFFICIENT’ object.
fluid1_drag_force	Specifies drag force in low VF limit on 1st. fluid for AIAD model.
fluid2_drag_force	Specifies drag force in low VF limit on 2nd. fluid for AIAD model.
free_surface_drag_force	Specifies drag force in free surface sector of AIAD model.

Parent	Summary
momentum_transfer	Specifies momentum transfer models for a fluid pair.
