A performance of Lévy -- like process enriches this transport phenomenon. It is shown that an inhomogeneous convection flow, as a realization of the Lévy--like process, leads to superdiffusion of particles on the comb structure. A frontier case of superdiffusion that corresponds to the exponentially fast transport is studied and the log--normal distribution is obtained for this case.Disordered Systems and Neural Networkstext
