Coupled PDE with time varying boundary condition

Please login with a confirmed email address before reporting spam

∂C1/∂t + a*(∂C1/∂x) + (C1 - C2) = 0
∂C2/∂t + b*(∂C2/∂x) - (C1 - C2) = 0

C1, C2 are dependent variables , t is time , 0<x<1
a and b are constants.

boundary conditions are

(dC1/dt)@x=0 = m*( C1@x=0 - C1@x=1)
(dC2/dt)@x=1 = n*( C2@x=1 - C1@x=0)

initial conditions are C1 = 1 and C2 = 0
