Interpretation:
Using computer programming the value of Concentration profile and time required for given condition should be determined.
Concept introduction:
Equation used for calculating the diffusion is,
Fick's Law of diffusion: This law states that molar flux is directly proportional to concentration gradient. The law is stated as:
Where,
J is the molar flux defined as the number of atoms passing per unit area per unit time.
D is the diffusion coefficient in
Factors affection diffusion are as follows:
- Temperature
- Diffusion coefficient
Where,
Q is the activation energy in calorie/ mole.
R is universal gas constant in
T is the absolute temperature in kelvin.
Fick's Second law is applicable, which is used to define the non- steady state and diffusion of atoms. The equation is stated as:
Where,
erf is the error function.
