This subject covers fundamental concepts of diffusion and conservation within momentum, heat and mass transport. Use of these concepts is integral to the profession of Chemical Engineering. For example, heat exchangers are used throughout Chemical Engineering processes to transfer thermal energy from one stream to another. Knowledge of heat transport and momentum transport (ie fluid flow) is required to design a heat exchanger, other key pieces of Chemical Engineering process equipment, including distillation columns. Similarly, knowledge of mass transport is required to design other key Chemical Engineering processes, such as distillation.


The specific technical material covered in the course is as follows: Within momentum transport specific topics include Newton’s law of viscosity, viscosity of gases and liquids, conservation of momentum, velocity distributions in simple laminar flows, boundary layer concepts and turbulence and the Reynolds number. Within heat transport specific topics include Fourier’s law of conduction, thermal conductivities of gases, liquids and solids, conservation of thermal energy, steady-state temperature distributions in simple geometries, heat transfer resistance, thermal boundary layer concepts, the Nusselt and Prandtl numbers, definition and use of heat transfer coefficients and analysis of simple heat exchangers. Within mass transport specific topics include Fick’s first law of diffusion, diffusivities of gases, liquids and solids, binary mixture diffusion and conservation of mass, concentration distributions in simple binary systems including identifying appropriate boundary conditions, concentration boundary layer concepts, Schmidt and Sherwood numbers, definition and use of mass transfer coefficients.

Intended learning outcomes


On completion of this subject the student is expected to be able to:

  1. Describe the fundamental concepts of momentum, heat and mass transfer
  2. Apply these principles to the solution of problems in process engineering
  3. Continue study in the area of heat and mass transport with a solid foundation.
