If Pe > 1, then diffusion dominates and if Pe < 1, convection dominates. The journal provides the readers with free, instant, and The Pclet number, another dimensionless parameter described by P = U L D (where U = velocity, L = length of the channel, and D = diffusivity) determines whether the mass transport is dominated by diffusion or convection. Its physical significance can be inferred from its definition. Convection cannot take place in most solids because neither bulk current flows nor significant diffusion of matter can take place.
