Introduction to Fluid Dynamics, Spring 2013


  • This is a 3 credit course that is offered to students of the 6th and 8th semesters at IISER Pune. It is also offered over the National Knowledge Network to students at IISER Kolkata. It is taught by Dr Prasad Subramanian.

    This course will be useful for students wishing to gain an overview of the vast field of fluid dynamics. It will serve as a springboard for those who would like to go on to work in areas connected to fluid dynamics, such as astrophysics, aerodynamics, biofluid dynamics, computational fluid dynamics, etc.

    The course will be organized into the following (approximate) modules:

    1) The continuum hypothesis, kinematics, conservation laws: continuity equation, Euler and Navier-Stokes equations (chapters 1, 3 and 4, Kundu & Cohen, 3 weeks)

    2) Dimensionless numbers, dynamic similarity, aerodynamics (chapters 8 and 15, Kundu and Cohen, 2 weeks)
    Pdf file of lectures for module 2

    Quiz 1

    3) Compressible flows, speed of sound, shocks (2 weeks, chapter 16, Kundu and Cohen, also relevant parts from Physics of Fluids and Plasmas, Arnab Rai Choudhuri)

    4) Fluid instabilities and turbulence (chapters 12 and 13, Kundu and Cohen, also relevant parts from Physics of Fluids and Plasmas, Arnab Rai Choudhuri, 2 weeks)
    Pdf file of lectures for module 4

    5) Applications of fluid dynamics in Astrophysics: e.g., Astrophysical jets, the de Laval nozzle, spherical accretion onto compact objects, the solar wind (2 weeks)
