Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

2. Compressibility

Course subject(s) Module B: Aerodynamics

Welcome to lecture 2! This lecture will cover compressibility, but for that we first need to start with the basics: thermodynamics.

Sorry but there don't seem to be any downloads..

Most of you will have heard of the “sound barrier”. What happens when we reach the speed of sound, and how can we find how fast that is? Mr. Timmer will explain these and other topics in this video!

In this video, Mr. Timmer will show you how to use and apply all the formulas we have lined up: in this case for a supersonic wind tunnel.
