3. COMPONENT DESCRIPTION
3.13 Splitter - SP
There are three splitter components:
• one for exhaust gas (from the SOFC)
• one for the LiBr solution (in the ABS)
• one for the water/steam (in the ABS)
They all work the same basic way, just with different species.
No chemical reaction takes place in the splitter, so the mass flow of each
species (j) into the component is the sum of the two mass flows of that
species out the component. The fraction of the inlet flow which goes to
the first outlet is termed α (and the fraction for the other outlet then becomes
(1-α)):
ṁ o,1,j = ṁ i ,j α (3.96)
ṁ o,2,j = ṁ i ,j (1 − α) (3.97)
The mixer is adiabatic and hence the temperature of the two outlet are
equal to the inlet temperature:
T o,1 = T i (3.98)
T o,2 = T i (3.99)
The pressure at the two outlets can be different (due to other
components in the system), so the splitter includes two different pressure
loss parameters (of which none may be positive).
p o,1 = p i + ∆p 1 (3.100)
p o,2 = p i + ∆p 2 (3.101)
