Excluded Combination of Modules

Aims

  • To introduce a mathematical description of fluid flow and other continuous media to familiarise students with the successful applications of mathematics in this area of modelling.
  • To prepare students for future study of advanced topics.

Content

  • Kinematics: Eulerian and Lagrangian pictures, velocity field, streamlines and stream functions.
  • Compressibility, vorticity and circulation, integrals over material domains.
  • Dynamics of ideal fluids: derivation of the incompressible Euler equations, energy, vorticity dynamics, circulation and rotating frames.
  • Water waves: free-surface boundaries, linearisation, travelling and standing waves.
  • Compressible flow: barotropic fluids, sound waves, nonlinearity.
  • Hydrodynamic stability: normal mode analysis, Rayleigh-Taylor and Kelvin-Helmholtz instabilities.
  • Dynamics of viscous fluids: Newtonian fluids, derivation of the Navier-Stokes equations, exact solutions, dynamical similarity, boundary layers.

Learning Outcomes

Subject-specific Knowledge:
  • By the end of the module students will: be able to solve novel and/or complex problems in Fluid Mechanics.
  • Have a systematic and coherent understanding of theoretical mathematics in the field of Fluid Mechanics.
  • Have acquired coherent body of knowledge of these subjects demonstrated through one or more of the following topic areas:
  • Kinematics and dynamics of fluid flows, compressible flow, hydrodynamic stability and dynamics of viscous fluids.
  • Equations of motion and their derivation for fluids.
Subject-specific Skills:
  • In addition students will have specialised mathematical skills in the following areas which can be used with minimal guidance: Modelling.
  • They will be able to formulate and use mathematical models in various situations.
Key Skills:

    Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

    • Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
    • Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
    • Formatively assessed assignments provide practice in the application of logic and high level of rigour as well as feedback for the students and the lecturer on students' progress.
    • The end-of-year examination assesses the knowledge acquired and the ability to solve predictable and unpredictable problems.
