PHREEQC: Added new Basic functions MCD_JTOT and MCD_JCONC that return
|
||||||
|
multicomponent diffusion fluxes. MCD_JTOT returns the value of equation
|
||||||
|
10 in the description of the TRANSPORT keyword in the PHREEQC 3 manual
|
||||||
|
for an aqueous species. MCD_JCONC returns the flux calculated by the
|
||||||
|
first term of equation 10. The functions ignore interlayer diffusion
|
||||||
|
and only apply to multicomponent diffusion. Here are Basic examples.
|
||||||
|
Uphill diffusion occurs when the two functions have opposite signs.
|
||||||
|
|
||||||
|
10 jtot = MCD_JTOT("Cl-")
|
||||||
|
20 jconc = MCD_JCONC("Cl-")
