Functions
void	cs_coal_source_terms_scalar (cs_field_t *fld_scal, cs_real_t smbrs[], cs_real_t rovsdt[])
	Compute scalar source terms for pulverized coal flame.

Detailed Description

Coal combustion model: source terms computation.

Function Documentation

cs_coal_source_terms_scalar()

void cs_coal_source_terms_scalar	(	cs_field_t *	fld_scal,
		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 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:

• 
• 

Here are and (they contain ) smbrs in kg variable/s: i.e.: - for velocity

• for temperature
• for enthalpy
• rovsdt

Parameters

[in]	fld_scal	pointer to scalar field
[in,out]	smbrs	explicit second member
[in,out]	rovsdt	implicit diagonal part
