ADVANCED FLUID DYNAMICS

Oxford Master Course in Mathematical and Theoretical Physics
("MMathPhys")
&
Centre for Postgraduate Training in Plasma Physics and High Energy Density Science



magnetic field



Prof Alexander Schekochihin and Dr Paul Dellar
TA: Luuk Metselaar

This is an MMathPhys course which we also expect to be of interest to graduate students specialising in the physics (or applied mathematics) of gases and plasmas, astrophysics, and condensed matter.

PART I: MAGNETOHYDRO-
DYNAMICS
Lectures 1-10 Prof Alexander Schekochihin
MHD equations: conservation laws in a conducting fluid; Maxwell stress/magnetic forces; induction equation; Lundquist theorem, flux freezing, amplification of magnetic field. MHD in a strong guide field: MHD waves; high-beta and anisotropic limits and orderings; incompressible MHD, Elsasser MHD, Reduced MHD. Static MHD equilibria, force-free solutions, helicity, Taylor relaxation. Energy principle. Instabilities: interchange, Z-pinch.

Problem Set 1

They will be occasionally updated
during this term. The current
version is of 13.02.17.
I will be very grateful to those
of you who offer criticisms,
suggestions or point out errors.

READING LIST
(we will provide detailed reading recommendations from the list below as the course progresses)

PART I: Here are four very different textbooks, all well worth reading:
1. P. A. Sturrock, Plasma Physics (CUP 1994) Chapters 11-16 cover MHD (~100 pages)
2. R. M. Kulsrud, Plasma Physics for Astrophysics (Princeton U Press 2005) Chapters 3-7 cover MHD (~150 pages)
3. P. A. Davidson, An Introduction to Magnetohydrodynamics (CUP 2001) Part A covers the fundamental MHD (~300 pages)
4. H. Goedbloed & S. Poedts, Principles of Magnetohydrodynamics (CUP 2004) (~600 pages)
