Aim

Momentum, heat and mass transport phenomena are unified and a microscopic interpretation in the frame of statistical mechanics and the kinetic theory of gases is presented. The three-dimensional, time-dependent balances are derived and various diffusion and convection problems are formulated and solved. Emphasis is placed in mass and combined mass-heat transfer. Main goal of the course is to develop the background for the analysis and design of transport processes encountered in the chemical and power industry.

Syllabus
  • Deviation from thermodynamic equilibrium: transport phenomena. Examples of complex transport phenomena.
  • Unification of molecular transport laws of Fourier, Fick and Newton.
  • Microscopic interpretation of molar transport of momentum, heat and mass on the basis of kinetic theory of gases and statistical mechanics.
  • Formulation of the differential balance for a general transport property. The balance statement for a fixed control volume.
  • Molecular and convective transport. The vectorial nature of heat and mass flux. The tensorial nature of momentum flux. Generalization of molecular transport laws in three dimensions.
  • Boundary conditions on solid walls and fluid interfaces.
  • Applications of one‐dimensional transport: Steady heat conduction through an electrical wire. Viscous heating of a lubrication bearing. Inclined film flow. Analysis of a diaphragm cell for measuring diffusivity.
  • Convective transport: laminar boundary layer, mass/heat transport in a pipe, mixing cup temperature/concentration.
  • Emphasis on mass transfer: definitions and explanation for the convection induced by mass transfer. Equimolar counterdiffusion in gases. Unimolecular diffusion in gases. Diffusion with heterogeneous and homogeneous chemical reaction. Diffusion through solids. Knudsen diffusion. Diffusion through membranes.
  • Definition of the mass transfer coefficient. Dimensional analysis: the Schmidt and Sherwood numbers. The Reynolds and Chilton‐Colburn analogies between heat, mass and momentum transport.
  • Mass transfer across interfaces.
  • Simultaneous heat and mass transfer.
