Diffusion Equation - Finite Cylindrical Reactor

Diffusion Equation - Finite Cylindrical Reactor

Solution for the Finite Cylindrical Reactor. Let assume a uniform reactor (multiplying system) in the shape of a cylinder of physical radius R and height H. This finite cylindrical reactor is situated in cylindrical geometry at the origin of coordinates. In order to solve the diffusion equation, we have to replace the Laplacian by its .
