Staggered Water Current Turbine Arrangement for Flow Diversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water current turbine farm layouts, typically arranged in regular grids or arrays, suffer from reduced power generation due to water flow diverting around individual turbines, leading to economic viability issues.
Innovation Solution
A method to determine an optimized arrangement of water current turbine units by considering flow characteristics, including spacing closer to boundaries and staggered formations, allowing diverted flow to be utilized by subsequent units, thereby increasing energy capture and power output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If turbine units are arranged in a regular grid array, then the layout is simple and easy to deploy, but water flow diverts around the array reducing power generation
Solution Approach 1:
The patent applies asymmetry by transitioning from a symmetric regular grid array to an asymmetric staggered formation. The turbine units are arranged in offset rows where units in alternating rows are positioned at different longitudinal locations, creating an asymmetric pattern that disrupts flow diversion and enhances power capture while remaining deployable.
Solution Approach 2:
The patent introduces a longitudinal dimension to the array layout by staggering turbine units along the flow direction. Instead of only transverse spacing in a single plane, the staggered formation adds longitudinal offset between alternating rows, creating a three-dimensional arrangement that captures diverted flow more effectively.
2Ease of operation
If turbine units are spaced apart in regular rows, then maintenance access is improved, but flow volume through turbines is reduced
Solution Approach 1:
The patent segments the turbine array into multiple staggered rows with alternating positions. This segmentation allows maintenance personnel to access individual turbine units by navigating through the staggered gaps between rows, while simultaneously creating flow paths that guide water through more units by reducing diversion around the array edges.
3Area of stationary object
If turbine units are clustered densely, then space utilization is improved, but flow diversion around clusters increases
Solution Approach 1:
The patent applies dynamics by creating a flexible staggered formation that adapts flow patterns through its asymmetric structure. The offset rows create varying flow paths that dynamically redirect water through clustered units rather than allowing uniform diversion, maximizing space utilization while minimizing energy loss.

Function Achieved in This Case
This approach maximizes the volume of water flowing through turbine units, enhancing overall power yield and economic viability by managing flow direction and packing density within the turbine farm.
Implementation Method 1
The rotor assembly includes a plurality of rotor blades that are driven by the water flow, so as to turn an input shaft of the drivetrain. As water flows past the power generating apparatus 1, the rotor assembly is caused to rotate
Implementation Method 2
The turbine unit 2 includes a shaft driven generator connected using a drivetrain to a rotor assembly... the generator is able to generate electrical power
