Abstract
Fluid processing apparatus comprises a fluid-handling manifold comprising a manifold body having at least a first fluid duct and a second fluid duct. The first and second fluid ducts are in fluid communication with each other at a microfluidic junction of the fluid-handling manifold. The manifold body further comprises a transducer operative to generate ultrasonic acoustic traveling wave radiation into fluid in the microfluidic junction from an active surface toward a non-reflective boundary of the microfluidic junction. The microfluidic junction is operative to pass fluid received from the first and second duct, with micro-mixing effected by the traveling wave radiated into the junction during the fluid flow.

Fluid processing apparatus comprising a fluid-handling manifold comprising:
- a manifold body having fluid ducts comprising at least a first fluid duct, a second fluid duct, a microfluidic junction, and an internal fluid duct, the first fluid duct and the second fluid duct being in fluid communication with each other at the microfluidic junction, the microfluidic junction being operative to pass into the internal fluid duct a local fluid flow comprising fluid received from the first fluid duct and fluid received from the second fluid duct;
- a transducer operative to generate ultrasonic acoustic traveling wave radiation of at least one wavelength into local fluid flow from a first surface area of the fluid ducts toward a second surface area of the fluid ducts, wherein the second surface area is directly opposite and not more than 300 microns from the first surface area;
- wherein the second surface area is non-reflective of said wavelength;
- and
- a sensor integral with the fluid-handling manifold and operative to detect a condition of fluid in the manifold body.
