Acoustic streaming is a steady flow in a fluid driven by the absorption of high-frequency sound waves, resulting in momentum transfer from the acoustic field to the fluid. This phenomenon is utilized in various applications, including enhancing mixing processes and improving heat transfer in industrial systems.

Acoustic Streaming

High-frequency sound waves, often exceeding 20 kHz, are used in various applications such as medical imaging and industrial non-destructive testing due to their ability to provide detailed information about the internal structure of objects. These waves are characterized by their short wavelengths, which allow them to penetrate materials and reflect off small features, making them invaluable for precision diagnostics and analysis.

High-frequency Sound Waves

Momentum transfer refers to the process by which momentum is exchanged between objects or systems, often occurring during collisions or interactions in fluid dynamics. It's a fundamental concept in physics that explains how forces are transmitted and how motion is affected in both macroscopic and microscopic systems.

Momentum Transfer

Acoustic field

Fluid dynamics is a branch of physics that studies the behavior of fluids (liquids and gases) in motion and the forces acting on them. It is essential for understanding natural phenomena and designing systems in engineering disciplines, including aerodynamics, hydrodynamics, and meteorology.

Fluid Dynamics

Mixing processes are essential in various scientific and industrial applications to achieve homogeneity and ensure uniform distribution of components. These processes are influenced by factors such as fluid dynamics, material properties, and mixing techniques, which must be optimized for efficiency and effectiveness.

Mixing Processes

Heat transfer is the process by which thermal energy moves from a region of higher temperature to a region of lower temperature. It occurs through three primary mechanisms: conduction, convection, and radiation, each with distinct characteristics and applications.
