Abstract
The Fast Fourier Transform method has been applied to light and voltage fluctuations in a low power (<5 kW) dc plasma torch burning in argon. The influence of the gas flow on the development of turbulence in the plasma jet has been studied. The temporal and spatial non-homogeneities observed in the plasma flow have been linked to the dynamic processes in a dc plasma torch.Keywords
