Shape curvature effects in viscous streaming
WebbViscous streaming arises when an immersed body undergoes small-amplitude oscillations in a viscous fluid, and it is perhaps the most efficient way to use inertia at the … WebbViscous streaming refers to the rectified, steady flows that emerge when a liquid oscillates around an immersed microfeature, typically a solid body or a bubble. The ability of such …

Webb24 aug. 2024 · The results show that the large curvature and aspect ratio reduce the fluid speed gradually but that the flow rate promotes fluid velocity. The pumping rate is a decreasing function of the curvature and aspect ratio; however, reverse pumping can occur for large curvature values. WebbRecent studies on viscous streaming flows in two dimensions have elucidated the impact of body curvature variations on resulting flow topology and dynamics, with opportunities …
