heat and mass transfer

... corresponds to thatof heat conduction, whilst mass transfer in a flowing fluid, known for short asconvective mass transfer corresponds to convective mass transfer. Mass transfer by diffusion and convection ... only sorts of mass transfer. Radiative heat transfer has no corresponding mass transfer process.1.4.1 DiffusionThe calculation of mass transfer by diffusion requires several definitions and rela-tionships ... velocity is small and drops to zero at the surface. Therefore closeto the surface the convective part of mass transfer is very low and the diffusive part, which is often decisive in mass transfer, dominates.1.2...
