1Productivity
If traditional baffles are used for mixing additives into fluid streams, then mixing is achieved, but pressure drop increases and mixing efficiency is insufficient
Solution Approach 1:
The mixing element is segmented into multiple V-sections with forward and rearward facing legs, creating multiple flow paths and mixing zones within a single element. This segmentation allows for progressive mixing of the additive into the fluid stream, improving mixing efficiency while distributing the pressure drop across multiple smaller obstacles rather than one large baffle.
Solution Approach 2:
The V-sections feature asymmetric geometry with forward-facing and rearward-facing legs of different orientations. The forward-facing V-sections have apexes pointing upstream while rearward-facing V-sections have apexes pointing downstream, creating asymmetric flow patterns that enhance mixing through complex velocity vectors while maintaining lower pressure drops compared to traditional symmetric baffles.
2Area of stationary object
If mixing elements create complex velocity vectors to enhance mixing, then contact area between fluids increases, but pressure drop increases
Solution Approach 1:
The V-section configuration introduces three-dimensional flow patterns by creating velocity vectors in multiple directions (upstream, downstream, lateral). The forward and rearward facing legs generate flow components in different spatial dimensions, increasing the contact area between additive and fluid stream through三维 mixing patterns rather than simple planar deflection.
Solution Approach 2:
The geometry parameters of the V-sections (leg angles, apex positions, spacing between sections) are optimized to achieve the desired balance between mixing effectiveness and pressure drop. By adjusting these geometric parameters, the flow vectors are tuned to maximize fluid contact area while minimizing energy loss.

AI summary
A material distributing and mixing apparatus. A conduit having a fluid inlet and fluid outlet houses a mixing element The mixing element includes rectangular segments forming forward facing V-sections and rearward facing V-sections. The forward facing V-sections form vertical apexes that face an incoming fluid stream while additive inlet ports are positioned proximate thereto. The forward facing V-sections are positioned proximate to the top and bottom surfaces of the conduit while the rearward facing V-sections form apexes which are substantially horizontal, the rearward facing V-sections being positioned proximate the vertically extending side walls of the conduit.
