TITLE Example 12a.--Advective and diffusive transport of heat and solutes.
|
|
Constant boundary condition at one end, closed at other.
|
|
The problem is designed so that temperature should equal Na-conc
|
|
(in mmol/kgw) after diffusion. Compares with analytical solution
|
|
for 20-cell and 60-cell models.
