Function Documentation

cs_fan_build_all()

void cs_fan_build_all	(	const cs_mesh_t *	mesh,
		const cs_mesh_quantities_t *	mesh_quantities
	)

Define the cells belonging to the different fans.

Parameters

[in]	mesh	associated mesh structure
[in]	mesh_quantities	mesh quantities

cs_fan_cells_select()

void cs_fan_cells_select	(	void *	input,
		cs_lnum_t *	n_cells,
		cs_lnum_t **	cell_ids
	)

Selection function for cells belonging to fans.

This function may be used for the definition of postprocessing meshes.

Parameters

[in,out]	input	pointer to input (unused here)
[out]	n_cells	number of selected cells
[out]	cell_ids	array of selected cell ids (0 to n-1 numbering)

cs_fan_compute_flows()

void cs_fan_compute_flows	(	const cs_mesh_t *	mesh,
		const cs_mesh_quantities_t *	mesh_quantities,
		const cs_real_t	i_mass_flux[],
		const cs_real_t	b_mass_flux[],
		const cs_real_t	c_rho[],
		const cs_real_t	b_rho[]
	)

Compute the flows through the fans.

Parameters

[in]	mesh	mesh structure
[in]	mesh_quantities	mesh quantities
[in]	i_mass_flux	interior faces mass flux
[in]	b_mass_flux	boundary faces mass flux
[in]	c_rho	density at cells
[in]	b_rho	density at boundary faces

cs_fan_compute_force()

void cs_fan_compute_force	(	const cs_mesh_quantities_t *	mesh_quantities,
		cs_real_3_t	source_t[]
	)

Compute the force induced by the fans (needs a previous calculation of the flows through each fan).

Parameters

[in]	mesh_quantities	mesh quantities
[in]	source_t	explicit source term for the velocity

cs_fan_define()

void cs_fan_define	(	int	fan_dim,
		int	mode,
		const cs_real_t	inlet_axis_coords[3],
		const cs_real_t	outlet_axis_coords[3],
		cs_real_t	fan_radius,
		cs_real_t	blades_radius,
		cs_real_t	hub_radius,
		const cs_real_t	curve_coeffs[3],
		cs_real_t	axial_torque
	)

Fan definition (added to the ones previously defined)

Fans are handled as explicit momentum source terms at the given location, based on the fan's axis and diameter. The fan's pressure characteristic curve is defined by 3 coefficients, such that: . An axial torque may also be defined for the 3D model.

Parameters

[in]	fan_dim	fan dimension: 2: pseudo-2D (extruded mesh) 3: 3D (standard)
[in]	mode	mode: 0: fan 1: wind turbine

[in]	fan_radius	fan radius
[in]	blades_radius	blades radius
[in]	hub_radius	hub radius
[in]	curve_coeffs	coefficients of degre 0, 1 and 2 of the pressure drop/flow rate characteristic curve
[in]	axial_torque	fan axial torque
