Hallo everyone,
I have a 1-D diffusion equation with decay as
dA/dt = d2A/dx2-L*A
with initial condition C(x,0)=C0=exp(-ax)
and boundary condition= -Ddc/dx = I0
where L= decay constant
A = certain concentration
the concentration A is not in equilibrium. We can solve the above equation for equilibrium putting dA/dt=0.
The equilibrium concentration can be reached in time t.
How can I determine the time that it takes to reach equilibrium concentration?
Thank you
help would be greatly appriciated
