[out]cell_idsarray 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[] )

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: $\delta P = C_0 + C_1.flow + C_2.flow^2$. An axial torque may also be defined for the 3D model.

Parameters

[in]modemode: 0: fan 1: wind turbine
[in]inlet_axis_coordsintersection of axis and inlet face
