  • First semester 2016 (Day)


The continuum hypothesis; notion of a fluid particle; pathlines and streamlines. Eulerian and Lagrangian frameworks; the material derivative. Conservation of mass; incompressibility; streamfunctions. Forces acting on a fluid; the stress tensor; conservation of momentum; the constitutive relation; the incompressible Navier-Stokes equations. Boundary conditions. Exact solutions of Navier-Stokes equations. Non-dimensionalization and dimensional analysis; Reynolds number. Low Reynolds number flows. Vorticity; circulation; Helmholtz' vorticity equation; properties of vorticity; Kelvin's circulation theorem. Lubrication theory. Inviscid flows; potential flows. Boundary layer equations and flows.


On completion of this unit students will be able to:

  1. Explain the scope of fluid dynamics in the physical sciences;
  2. Understand the mathematical description of fluid motion;
  3. Summarise the derivation of the equations of incompressible fluid motion;
  4. Understand and apply the process of scaling to simplify the governing equations for viscous and inertia dominated flows;
  5. Understand and apply the process of scaling to lubrication and boundary layer flows;
  6. Solve the governing and reduced equations in simple situations and understand the physical implications of the solutions and their limitations.
