US 2026/0077319 A1 · NANOBUBBLE GENERATION IN FLUID FLOW

Abstract

A nanobubble generating device includes a tubular structure and open channels. The tubular structure has an inner surface. The tubular structure defines an inlet port and an outlet port on opposing ends of the tubular structure for enabling fluid flow through the device. The open channels are disposed on the inner surface of the tubular structure. The open channels extend along at least a portion of a length of the tubular structure between the inlet port and the outlet port. A fluid is flowed across the open channels. Nanobubbles are generated in the fluid in response to flowing the fluid across the open channels.
