Effects of Supplied Gas on Plasma-Induced Liquid Flows

In this work, we investigated the effects of supply gas (helium and argon gases) on plasma-induced liquid flows using particle image velocimetry (PIV). The results indicated that only the downward flow that extended to the liquid depth direction was generated when helium gas was supplied. However, t...

Summary:In this work, we investigated the effects of supply gas (helium and argon gases) on plasma-induced liquid flows using particle image velocimetry (PIV). The results indicated that only the downward flow that extended to the liquid depth direction was generated when helium gas was supplied. However, the liquid flows switched with the increase in voltage when argon gas was supplied. We also discovered current waveforms and the optical emission spectroscopy results were greatly changed with the types of plasma-induced liquid flows. According to the experimental results for the argon gas, we also successfully switched and controlled the plasma-induced liquid flow by changing the voltage only.
