Insert T'(y)+T(y)+A instead of T''(y) in the expression for C''(y).
Are A and B nonlinear expressions ? If they are simply constants as they seem to be, your system is linear and can easily be solved analytically. Use "dsolve".

Sorry, no.
The code for the 4-equations model with interface condition should suffice for a transfer on your own to the Bessel function model.
If you have specific questions, you can come here and ask.

@Torsten, Thanking you sir, for reply. Actually that code was almost correct some syntax error, it was showing, which I am not able to capture. If you will suggest any changes, I will proceed accrodingly.
Thank you
