1. A method, comprising:
supplying a plasma-generating gas to a plasma generating device having an outlet;
applying energy to the plasma-generating gas according to a predetermined energy pattern; and
discharging, in response to applying the energy, a plasma flow from the outlet of the plasma generating device, the plasma flow having a periodic pattern including a base plasma flow and a pulse plasma flow,
the base plasma flow having a first temperature at the outlet of the device, and the pulse plasma flow having a second temperature at the outlet of the device that is greater than the first temperature,
the base plasma flow having a first density at the first temperature, and the pulse plasma flow having a second density at the second temperature, the first density being at least two times the second density,
the base plasma flow having a first speed of sound, and the pulse plasma flow having a second speed of sound that is at most four times greater than the first speed of sound.
