Shock Diamonds are diamond-shaped structures appearing in the super-sonic flow exhaust from a propelling nozzle. Although very common in the exhaust of aerospace propulsion system, the phenomenon may also appear in other systems. Using standard laboratory equipment, construct a setup to effectively observe Shock Diamonds, specifying the important parameters and methodological considerations employed in their creation and observation. Investigate the dependence of the shape and number of diamonds on the important parameters. What properties of the gas and jet can be inferred from your observations?
