Hi guys,
I want to solve a convection-diffusion equation with an absorption source term (Liner Driving Force model and Langmuir-Freundlich isothermals), but I don't know how to linearise this source term. Please see the following equations: ![]() ![]() ![]() where c is the variable, and others are constant. I wonder how to linearise this ![]() |

One typically writes the source term as a linearization around a 0 state (i.e., previous iteration value)
![]() Hopefully, you can do ![]() |
