Homework Statement
We let a dye diffuses into an environment of dimension L. We inject that dye into a box by one face, at t = 0 on x = 0. The linear density c follows that equation :
with the conditions :
Homework Equations
/ questions[/B]a. nondimensionalize the equations and the conditions
b. reveal a term homogeneous to time, and its signification
c. compare the characteristic lenghts of these equation systems
The Attempt at a Solution
By nondimensionalize this equation, I found this :
But I think it's wrong... I use the "formal way" to nondimensionalize the equation as shown in the Khan academy video on youtube.
May I ask for help ?
Thanks a lot
