Flow Path-Forming Member for Uniform Cooling of Ni-Based Alloy Disks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cooling disk-shaped metal materials, such as those made of nickel-based or titanium-based alloys, face challenges in achieving uniform cooling rates due to gas or liquid flow inhibition at complex shapes, leading to ineffective cooling, especially at the radial center and areas with lower flow rates.
Innovation Solution
A method involving a flow path-forming member that creates a constricted fluid flow path on the surface of the material, increasing fluid flow rates through the Venturi effect, allowing for localized cooling by directing the fluid flow to specific areas, thereby enhancing cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If gas or liquid is sprayed from a fixed nozzle toward a disk-shaped metal material in an open space, then the cooling process can be performed, but the flow of the sprayed gas or liquid is generated in the direction moving away from the surface, making it difficult for the gas or liquid to hit the surface effectively
Solution Approach 1:
A flow path-forming member is introduced as an intermediary component between the nozzle and the metal material surface. This member creates a constrained flow path that directs the cooling fluid along the surface, ensuring the fluid remains in contact with the target area rather than dispersing away, thereby improving cooling effectiveness.
Solution Approach 2:
The invention utilizes fluid dynamics principles by creating a controlled flow path that leverages the kinetic energy of the sprayed gas or liquid. The flow path-forming member channels this fluid flow to maintain velocity and direction toward the surface, preventing the fluid from moving away and ensuring continuous cooling contact.
2Area of stationary object
If a uniform gas or liquid flow is applied to the entire surface of the disk-shaped metal material, then the surface can be covered, but the flow is inhibited in the radial center part, creating a mass of gas or liquid with low flow rate
Solution Approach 1:
The flow path-forming member creates localized flow channels that adapt to different regions of the metal material surface. The flow path cross-section and direction are optimized for each local area, ensuring high-velocity fluid contact where needed rather than applying uniform flow that becomes stagnant in certain zones.
Solution Approach 2:
The cooling system is divided into multiple flow paths within the flow path-forming member, each directing fluid to specific regions of the surface. This segmentation prevents fluid stagnation by creating distinct flow channels that maintain velocity, rather than allowing a single uniform flow to become inhibited across the entire surface.
3Temperature
If gases and liquids are sprayed into an open space with a fixed volume between the metal material and pipes, then the cooling process can be performed, but the gases and liquids have decreasing flow rate at the time of spraying
Solution Approach 1:
The invention transitions from three-dimensional open space spraying to a two-dimensional constrained flow path along the surface. By confining the fluid flow to a defined path, the system maintains fluid velocity and prevents the flow rate decrease that occurs when fluid disperses in open space, ensuring consistent cooling performance.

AI summary
A method for producing a Ni- or Ti-based alloy product includes preliminarily processing a hot working material of a Ni- or Ti-based alloy after hot working into a predetermined shape; heating and holding the material at a solution treatment temperature to obtain a material held in a heated state; and cooling the material to obtain a solution-treated material. The cooling step includes placing a flow path-forming member having a space for forming a flow path for a fluid on a surface of the material held in a heated state to form a fluid flow path defined by the surface of the material held in a heated state and an inner surface of the space of the flow path-forming member; and allowing a fluid to flow in the fluid flow path so that the fluid in the flow path locally cools a part of the surface of the material.
