Fluid dynamics

In order to investigate the flow of gases ejected from pulsed nozzles used in different experimental setups, there is an ongoing research involving the "Schileren Imaging" technique.

Some of the experimental data is shown below:

1. Evaluation of the speed of the gas jet as a function of time by means of tracing the Mach angle of the Shock wave formations in air medium:

2. Correlation between the dimensions of the nozzle and the shape of the gas jet

3. Ejection of Isobutane at a pressure range of 3 bar into air

4. Ejection of Nitrogen at a pressure range of 10 bar into air

5. Ejection of Isobutane at a pressure range of 3 bar into vacuum

6. Ejection of Nitrogen at a pressure range of 3 bar into vacuum

7. Ejection of Nitrogen at a pressure range of 10 bar into vacuum
