Herringbone Fluid Guide Geometry for Lower Rear Pressure Drop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional herringbone-type fluid guiding units experience a pressure drop in fluid flow at the rear end part due to similar angles at the front and rear ends, reducing the coagulation rate of cells or fine particles.
Innovation Solution
The herringbone-type fluid guiding unit is designed with a front member that increases in lateral width in the rear direction and a rear member with a recessed or protruding part, forming an angle between imaginary lines that is greater at the front end than at the rear end, reducing pressure drop and improving recovery efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the herringbone pattern has the same angle at front and rear ends, then the structure is simple and easy to manufacture, but a pressure drop occurs in fluid flow at the rear end part when flow rate is increased
Solution Approach 1:
The patent applies asymmetry by making the herringbone pattern angles different at the front and rear ends of the channel. Specifically, the angle at the front end is smaller than the angle at the rear end, creating an asymmetric configuration that optimizes fluid flow characteristics and reduces pressure drop at the rear end while maintaining effective cell coagulation throughout the channel.
2Productivity
If the flow rate of fluid is increased, then the processing speed increases, but the pressure drop at the rear end part increases and coagulation rate decreases
Solution Approach 1:
The asymmetric angle design allows the channel to handle higher flow rates while maintaining coagulation efficiency. The smaller front angle and larger rear angle create optimized flow conditions that prevent excessive pressure drop even at increased flow rates, thereby maintaining reliable cell coagulation performance.
Solution Approach 2:
The patent changes the geometric parameters of the herringbone pattern by using different angles at different locations. This parameter variation optimizes the balance between flow rate and coagulation rate, allowing the system to operate effectively at higher flow rates without sacrificing coagulation efficiency.

AI summary
The present disclosure relates to a herringbone-type fluid guiding unit and an apparatus for concentrating fluid using same. The herring-bone type fluid guiding unit includes: a front member formed on a flow path and formed so that the width between the left side and the right side widens from a front end part toward the back, with respect to the flow direction of a fluid; and a rear member extending from the front member toward the back, wherein the rear member is provided with a recessed part that is recessed to a specific depth from the rear edge toward the front or with a protruding part that protrudes toward the back.
