Systems and methods are provided facilitating a steaming fluid flow utilizing acoustic waves. A system includes an acoustic wave generator and an acoustic coupler associated with the acoustic wave generator and coupling acoustic waves generated by the acoustic wave generator into a fluid. The acoustic coupler includes one or more acoustic coupling lenses, which direct the acoustic waves into the fluid and facilitate, at least in part, a streaming fluid flow in a common direction. In an enhanced embodiment, the common flow direction is at an angle to a direction acoustic waves are generated, and the acoustic coupling lens(es), in directing the acoustic waves into the fluid, redirects the acoustic waves from the direction of acoustic wave generation. The acoustic wave generator generates the acoustic waves in the megahertz or gigahertz range, for example, with a frequency of 20 MHz or higher.
