Up to this point, we have studied the physics of supersonic flows over objects creating shock and expansion waves. One thing you must have noticed is that these waves are stationary with respect to the object. In this lesson, we will leverage our understanding of stationary waves and explore the physics of traveling one-dimensional waves. We will analyze moving normal shock waves, acoustic waves, and centered expansion waves. Finally, we will combine our learning from all these phenomena and undertake a detailed analysis of the classic Sod shock tube problem, which is shown below.
Here are the accompanying handout slides for this lesson.
