Abstract: Abstract The evolution mode of the dynamic bubble around the arc burning zone plays an essential role in adversely affecting the stability of underwater wet welding (UWW) process. Ultrasonic wave-assisted UWW (U-UWW) provides such a… read more here.

Abstract: In this paper we develop a novel ray solver for the time-harmonic linearized Euler equations used to predict high-frequency flow–acoustic interaction effects from point sources in subsonic mean jet flows. The solver incorporates solutions to… read more here.
