Turbomachine Circulation Structure Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing turbomachines face challenges in easily integrating and optimizing circulation structures within their housings to enhance aerodynamic stability and compressor performance, particularly in areas with high aerodynamic loads where local stalls and surging occur.
Innovation Solution
A turbomachine design featuring a two-part structural housing divided radially into a front and rear area, allowing for the circulation structure to be easily integrated with adjustable flow guide elements that can be manufactured and assembled separately, enabling optimal alignment and adjustment to the application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a circulation structure is integrated into a turbomachine housing to optimize aerodynamic stability and compressor performance, then the aerodynamic stability and compressor load capacity are improved, but the complexity of manufacturing and installing the circulation structure increases
Solution Approach 1:
The circulation structure is divided into a front structural area and a rear structural area that can be manufactured and assembled separately. The housing is correspondingly divided into a front housing area and a rear housing area, allowing the circulation structure to be integrated in a modular fashion that reduces manufacturing and installation complexity while maintaining aerodynamic stability optimization
2Reliability
If the circulation structure is designed with fixed geometry to optimize specific flow conditions, then the aerodynamic performance is improved, but the adaptability to different applications and operating conditions deteriorates
Solution Approach 1:
The flow guide elements within the circulation structure can have different lateral distances from one another, different geometries and/or different positions relative to one another. This allows the circulation structure to be specifically adjusted to the respective application while maintaining optimized aerodynamic performance through locally tailored flow guidance
3Device complexity
If the circulation structure is designed as a single integrated component to simplify the overall design, then the design coherence is improved, but the ease of manufacture and installation deteriorates
Solution Approach 1:
The circulation structure is divided into a front structural area and a rear structural area that can be manufactured and assembled separately. This segmentation allows each area to be optimized for its specific manufacturing requirements and assembly considerations, improving ease of manufacture and installation while maintaining design coherence through the overall integrated configuration

AI summary
A turbomachine having at least one circulation structure is disclosed. The circulation structure has an annular space with baffle elements surrounding a main flow path and is open to the main flow path. A housing of the turbomachine to receive the circulation structure is divided in an axial plane into a front housing region and a rear housing region and the circulation structure is divided into a front structure region and a rear structure region in the axial plane of separation. A circulation structure divided into two parts in the axial direction and a method for the same is also disclosed.
