👉 Bleeding engineering, also known as bleeding or bleeding off, is a technique used in the design and manufacturing of mechanical systems, particularly in fluidic circuits and microfluidic devices. It involves intentionally introducing air bubbles into a fluid stream to create voids or channels within the system, which can then be removed through external means such as suction or gravity. This process is crucial for optimizing fluid flow, reducing pressure drops, and enhancing mixing efficiency in microfluidic applications. By strategically placing bleeder ports or using specific channel geometries, engineers can effectively "bleed off" excess fluid, ensuring that the system operates smoothly and efficiently. This technique is especially valuable in lab-on-a-chip devices, biosensors, and other miniaturized systems where precise control over fluid dynamics is essential.
