Tubular Turbine Cross-Section Adjustment for Flow Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe turbine devices in fluid transport networks, particularly in gas transport networks, suffer from reduced electrical energy yield due to fixed designs that are optimized for maximum fluid volume flow, leading to inefficiencies during fluctuating or reduced volume flows.
Innovation Solution
The pipe turbine device incorporates a cross-sectional adjustment mechanism, which includes a plate module with radially movable elements, allowing the flowable cross-sectional area to be adjusted based on the fluid volume flow. This mechanism ensures that the flow speed remains constant, optimizing the operation of the pipe turbine device and enhancing electrical energy production.

Engineering Contradiction Analysis
1Power
If the tubular turbine device is designed with a fixed cross-sectional area optimized for maximum fluid volume flow, then the electrical energy yield is maximized at nominal operation, but the electrical energy yield significantly reduces during fluctuating or reduced volume flows
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed cross-sectional area design into a dynamic, adjustable cross-sectional area system. The cross-sectional adjustment device enables the turbine to adapt its flow area in real-time according to varying fluid volume flows, allowing optimal electrical energy yield across different operating conditions rather than being fixed for nominal operation only.
Solution Approach 2:
The patent implements parameter changes by modifying the cross-sectional area parameter of the tubular turbine device. The cross-sectional adjustment device changes this geometric parameter dynamically, allowing the system to optimize performance across different volume flow conditions by adjusting the effective flow area to match the current operating conditions.
2Ease of manufacture
If the tubular turbine device uses a fixed-load design, then the structure is simpler and manufacturing is easier, but the device cannot efficiently handle time-dependent and fluctuating volume flows
Solution Approach 1:
The patent transforms the static fixed-load design into a dynamic system by introducing the cross-sectional adjustment device. This device enables the turbine to actively respond to fluctuating volume flows, significantly improving electrical energy yield under varying conditions while maintaining a relatively simple overall structure that can be manufactured with standard techniques.
