Fluid-Permeable Containment Walls for Corrosion and Abrasion Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containment structures face damage from corrosive or abrasive fluids due to direct contact, necessitating the use of specialty materials that are expensive and have limited use cases.
Innovation Solution
A support structure with a fluid-permeable wall and ports that allow fluid to pass through, forming a barrier between the wall and the contained material, using additive manufacturing to integrate the permeable wall within the outer wall, and controlling fluid flow to regulate temperature and mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialty materials (stainless steel, titanium, ceramics) are used to resist corrosion and abrasion, then the containment structure's resistance to fluid damage is improved, but the cost and manufacturing complexity increase
Solution Approach 1:
A fluid-permeable membrane is introduced as an intermediary barrier between the contained fluid and the containment structure wall. The membrane selectively permits certain fluids to pass through while blocking others, creating a protective interface that prevents direct contact between harmful fluids and the containment structure, thereby eliminating the need for expensive specialty materials
Solution Approach 2:
The containment structure employs a fluid-permeable membrane with controlled porosity that allows selective fluid passage. The membrane's porous structure enables beneficial fluids to pass through while blocking harmful corrosive or abrasive substances, providing protection through material selection rather than structural complexity
2Reliability
If a fluid barrier is introduced between the containment wall and the stored material, then protection from corrosive damage is improved, but the device complexity increases due to additional components
Solution Approach 1:
The containment structure is merged with the fluid-permeable membrane in a single integrated design. The membrane is positioned within the containment wall structure itself, combining the barrier function with the containment function into one unified component rather than adding separate protective layers
Solution Approach 2:
The fluid-permeable membrane serves multiple functions simultaneously: it acts as a selective barrier to block harmful fluids, allows beneficial fluid passage for containment operations, and provides structural integration within the containment wall. This multi-functionality reduces the need for additional specialized components
3Reliability
If the containment structure is designed for specific fluids, then the resistance to fluid damage is improved, but the adaptability to different fluid types decreases
Solution Approach 1:
The fluid-permeable membrane exhibits different permeability properties at different locations or for different fluid types. The membrane can be designed with varying pore sizes, compositions, or configurations in different regions to selectively permit or block specific fluids, allowing the same containment structure to handle multiple fluid types with different protection requirements
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
Reduces direct contact and damage to containment structures, enabling the use of less expensive materials and facilitating temperature regulation and material mixing within the structure.
Implementation Method 1
The fluid-permeable wall may include one or more passages or pores that permit the fluid to flow from a first side to a second side
Data Source
AI summary
Systems and methods are directed toward support structures for materials that include one or more flow passages to form a barrier between an inner wall of the support structures and the materials. The one or more flow passages may include ports or pores extending through a fluid-permeable material forming at least a portion of the support structure. A barrier fluid may be introduced at a first side of the inner wall and may be driven, such as using differential pressure, through the inner wall to from a barrier along a second side of the inner wall to reduce a likelihood of contact between the materials and the second side of the inner wall.
