What is it about?
The noise levels generated by supersonic transport are usually very high. This works numerically investigates the effect of realistic operating conditions of a nozzle system used to generate thrust for supersonic aerospace applications. It shows that a temperature increase in nozzle operation leads to an enhanced sound generation.

Why is it important?
This study allows to identify and understand the main noise generation mechanisms for supersonic propulsion systems. The findings about the flow physics can be used to design noise-reducing technologies.
