Course outcomes:

At the end of the course the student will be able to:

1. Apply knowledge of oblique and curved shock waves and shock wave structure

2. Solve problems related to hypersonic viscous effects

3. Model hypersonic wind tunnel testing.

 

Question paper pattern:

The SEE question paper will be set for 100 marks and the marks scored will be proportionately reduced to 60.

  • The question paper will have ten full questions carrying equal marks.
  • Each full question is for 20 marks.
  • There will be two full questions (with a maximum of four sub questions) from each module.
  • Each full question will have sub question covering all the topics under a module.
  • The students will have to answer five full questions, selecting one full question from each module.
