Investigation of Rayleigh instability in thermal plasma jet generated by plasma torch with external anode.
Coherent oscillations with frequency in the range 20-80kHhas been observed in thermal plasma jet close to the nozzle exit.From a phase shift of the oscillations along the,jet,the wave phase velocity was evalueted.T...

Preparation of concrete substrate for repair by continuous and pulsating oscillating water jets
The water jet ability to remove selectively degraded material can be further improved by introducing high-frequency pressure pulsation into the jet. A series of experiments was realized to compare the effects of both pulsating o...
