|
| Requisites: |
Before or while taking this module you must ( take PH12005 AND take PH22010 ) OR take PH32018 OR ( take PH10103 AND take PH20107 )
|
| Learning Outcomes: |
After taking this unit the student should be able to:
derive Euler's conservation laws for inviscid fluids;
determine whether the fluid continuum approximation is applicable and the relation between conservation laws and equations of state;
apply the relevant fluid dynamics frameworks for relativistic fluids and viscous fluids;
characterise different types of fluid flow;
demonstrate understanding of shock waves, sound waves and their differences;
apply fluid dynamics in various (astro-)physical contexts including atmospheres, Bondi accretion flow and pipe flow.
|
| Synopsis: | Further develop your understanding of the fundamental concepts and equations of fluid dynamics in a physical and astrophysical setting. You will learn about the behaviour of gases and liquids on earth, as well as a range of phenomena in astrophysics, from the life of single stars, interstellar and intergalactic gas to the evolution of entire galaxies and the Universe as a whole.
|
| Content: | Conservation laws in vector form and index notation; Continuum approximation and Boltzmann's equation; Lagrangian fluid dynamics; Streamlines, streaklines and polytropic gases; hydrostatics and atmospheres; Convection, Bernoulli's equation, vorticity, potential flow; Sound waves and Bondi accretion; Shock waves, self-similarity and explosions; Special relativistic fluid dynamics; Viscous flow; concepts in plasma physics; characterising fluids.
