Course content

Steady and un-steady diffusion in dilute and concentrated fluids in different geometries. The Fick and Stefan-Maxwell equations, multicomponent diffusion. Diffusion in porous media. Generalised equations for momentum, mass and heat flow. Laminar and turbulent boundary layers. Mass transfer models. Simultaneous heat and mass transfer and transfer analogies. Introduction to Matlab (Solving ordinary differential and partial differential equations, discretization).

Learning outcome

At the end of the course the students should know:
- Generalized equations for mass, momentum and heat.
- Reynolds and Gauss theorems.
- Combined diffusive and convective transport.
- Film- and penetration models for mass and heat transfer.
- Stefan-Maxwells equations for multi-component diffusion.
- Use of the generalized equations for mass, momentum and heat for specific examples.
- Transform pratical problems into mathematical equations.
- Solve the given set of equations either analytically or numerically.
- Matlab programming on a level of solving differential equations and partial differential equations, discretization.
- Numerical integration with Runge Kutta and finite difference discretization.

Learning methods and activities

Lectures with worked-through examples. Compulsory exercises where 3 will contribute to the final mark. The exercises partially use Matlab. Continuous evaluation forms the basis for the final mark. This comprises written final exam (80%) and three exercises (20%). If there is a re-sit examination, the examination form may change from written to oral.
