Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flow of flowable materials through conduits experiences issues such as erosion, uneven deposition, turbulence, head loss, and increased energy consumption due to laminar flow profiles, particularly in piping systems with abrasive materials.
Innovation Solution
A material flow modifier that transforms laminar flow into rotational or cyclonic flow by using a device with an exterior tubular body, interior tubular body, and helical vanes to centralize flow towards the conduit's center, reducing friction and maintaining particle suspension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If laminar flow is maintained in the conduit, then flow stability is preserved, but friction loss increases and flow velocity reduces
Solution Approach 1:
The patent applies the dynamics principle by transforming the static laminar flow into a dynamic rotational flow pattern. The flow modifier device introduces helical vanes that convert axial flow into rotational flow, making the flow pattern dynamic rather than static. This dynamic rotational flow reduces friction loss while maintaining flow stability through continuous motion along the conduit centerline.
Solution Approach 2:
The patent applies parameter changes by altering the flow profile parameters from a parabolic laminar distribution to a rotational flow distribution. The flow modifier changes the velocity distribution parameter, concentrating flow toward the centerline and reducing wall friction. This parameter transformation resolves the contradiction by changing how flow stability is achieved while reducing energy loss.
2Device complexity
If conventional piping is used for abrasive materials, then system simplicity is maintained, but erosion of the conduit occurs
Solution Approach 1:
The patent applies the intermediary principle by introducing a flow modifier device as a mediator between the abrasive material and the conduit wall. This intermediary device redirects the flow path, preventing direct contact between abrasive particles and the conduit wall. The flow modifier serves as a protective intermediary that maintains system simplicity while eliminating erosion through flow redirection.
Solution Approach 2:
The patent applies segmentation by dividing the flow into multiple rotational components through helical vanes. This segmentation of the flow path causes particles to follow spiral trajectories rather than direct linear paths against the wall. The segmented rotational flow distributes particle impact away from the conduit wall, reducing erosion while maintaining overall system simplicity.
3Productivity
If higher pumping pressures are used to mitigate head loss, then flow rate increases, but energy consumption increases
Solution Approach 1:
The patent applies parameter changes by modifying the flow profile parameter from laminar to rotational flow. This parameter change reduces the head loss coefficient, allowing the same flow rate to be achieved with lower pumping pressure. The rotational flow parameter transformation directly addresses the energy-flow rate contradiction by changing the flow mechanics rather than increasing pressure.
Solution Approach 2:
The patent converts the harmful effect of head loss into a benefit by using the flow modifier to create rotational flow that actually reduces friction. Instead of fighting head loss with higher pressure, the invention transforms the flow pattern to eliminate the cause of head loss. This converts what would be a harmful energy loss into a beneficial flow characteristic that reduces energy consumption while maintaining productivity.
4Object-affected harmful factors
If long radius elbow fittings are used, then erosion is reduced, but space requirement increases
Solution Approach 1:
The patent applies the extraction principle by removing the need for long radius elbow fittings through the flow modifier device. The flow modifier extracts and redirects the flow path within the existing conduit geometry, achieving erosion protection without requiring additional space. This takes out the space-consuming long radius fitting while retaining the erosion protection function through active flow management rather than passive geometry.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances flow efficiency, reduces erosion, minimizes energy consumption, and maintains uniform flow by centralizing flow, preventing particle deposition and turbulence, while promoting continuous flow.
Implementation Method 1
A material flow modifier in accordance with one or more embodiments of the invention made herein enables flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a rotational flow profile - i.e., sometimes referred to as cyclonic or vortex flow
Implementation Method 2
Flowable material at the surface of the flow passage 10 exhibits considerable friction and zero flow velocity, thereby reducing velocity of the flowable material even at a considerable distance from the surface of the flow passage 10
Implementation Method 3
Additionally, due to centrifugal force, heavier solids and particulates are generally thrown to the outside wall as the flowable material changes direction and tend to continually scour the outer wall

AI summary
Material flow modifiers as disclosed herein overcome drawbacks associated with known adverse flow conditions (e.g., surface erosion, head losses, particulate drop-out, and the like) that arise from flow of certain types of materials (e.g., fluids, slurries, particulates, flowable aggregate, and the like) through a material flow conduit. Such material flow modifiers provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a rotational flow profile. Advantageously, the rotational flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow to overcome the aforementioned adverse flow conditions.
