Detailed Description

Coal combustion model: source terms computation.

Function Documentation

◆ cs_coal_source_terms_scalar()

void cs_coal_source_terms_scalar	(	int	fld_id,
		cs_real_t	smbrs[],
		cs_real_t	rovsdt[]
	)

Compute scalar source terms for pulverized coal flame.

Warning: the treatement is different from that of cs_user_source_terms.

We solve:

$rovsdt D(var) = smbrs$

rovsdt and smbrs already contain eventual user source terms. So they have to be incremented and not erased.

For stability reasons, only positive terms can be added in rovsdt. There is no contraint for smbrs.

In the case of a source term in , it has to be written:

$rovsdt = rovsdt + \max(-cimp,0)$

Here are and (they contain $\rho volume$ ) smbrs in kg variable/s: i.e.: - for velocity $kg . m . s^{-2}$

for temperature $kg . [degres] . s^{-1}$
for enthalpy $J . s^{-1}$
rovsdt $kg . s^{-1}$

Parameters

[in]	fld_id	scalar field id
[in,out]	smbrs	explicit second member
[in,out]	rovsdt	implicit diagonal part
