Rocket Nozzle Testing using Schlieren Imaging

Converging-diverging (De Laval) nozzle tested with compressed air across a chamber pressure range of 0-5 bar.

Nozzle test was part of a Part C Mechanical Engineering project at the Wolfson School of Mechanical & Manufacturing Engineering, Loughborough University.

What is the exit diameter of the nozzle?

@phph4v31aye. Hi. The exit diameter of the nozzle is 5.8mm.

How did you get a full-color schlieren setup? All I can find on the internet and in books is for black and white or false-color.

Hi. Sorry about the delayed response. The Schlieren effect was simply obtained by using a traditional setup using lenses and recording the video with a colour camcorder.

Thanks!
