Fluid Mechanics

Module aims

This module aims to enable students to extend their understanding of transport processes in fluid mechanics and of turbulent mixing. The course will highlight their significance in the areas of pollutant dispersion in the environment (e.g. the atmosphere, rivers, lakes or oceans) and in the modelling of natural and man-made hazards such as fires.

Learning outcomes

On successfully completing this course unit, students will be able to: 

  • Appreciate the physical processes that govern the transport of fluids and tracers.
  • Formulate problems modelling real world pollutant releases.
  • Apply analytical techniques to solve these problems.
  • Comment on the implications of the solutions.

Module syllabus

  • Overview of transport processes.
  • Properties of release and environment.
  • Modelling advection and diffusion.
  • Solutions to problems involving transport of pollutants in 1, 2 and 3D.
  • Forced releases and buoyancy.
  • Turbulent plumes in the environment and in models of building ventilation.
  • Fire and smoke modelling.
