Function Documentation

cs_lagr_coupling()

void cs_lagr_coupling	(	const cs_real_t	taup[],
		const cs_real_t	tempct[],
		cs_real_t	tsfext[],
		const cs_real_t	cpgd1[],
		const cs_real_t	cpgd2[],
		const cs_real_t	cpght[]
	)

Compute source terms for Lagrangian 2-way coupling.

Remarks

Source terms are computed for the starting cell of a particle during a given iteration. Even if particle exits the domain, it s necessary to compute a source term matching the exchange between the carrier fluid and the particle at the beginning of the time step. If cs_glob_lagr_time_step->nor == 2 and the particle interacts with a boundary, then the source terms are computed as if nor == 1.

Parameters

[in]	taup	dynamic characteristic time
[in]	tempct	thermal charactersitic time
[out]	tsfext	external forces
[in]	cpgd1	devolatization term 1 for heterogeneous coal
[in]	cpgd2	devolatization term 2 for heterogeneous coal
[in]	cpght	combustion term for heterogeneous coal
