Atmospheric pressure plasma jets generate highly reactive species with lifetimes spanning orders of magnitude. Species flux, relevant for plasma surface interaction, strongly depends on generation and transport processes. In non-thermal plasma jets at atmospheric pressure, flow induced convection determines the transport processes. This work compares diagnostic methods to measure flow in plasma jets.
