Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for analyzing and designing systems that utilize the jet-effect, such as the Coanda-jet-effect and electromagnetic jet-effect, are limited by the assumptions of continuum mechanics, which fail to accurately model fluid motion and energy conversion, leading to inefficiencies and paradoxical results in applications like wind turbines and thermodynamic systems.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If continuum mechanics assumptions are used to model fluid motion, then the modeling approach is simple, but the accuracy of fluid motion modeling deteriorates
Solution Approach 1:
The patent changes the fundamental parameters of fluid modeling from continuum mechanics assumptions to kinetic theory of matter parameters, considering fluid as composed of discrete molecules with specific properties. This allows accurate modeling of jet-effect phenomena while maintaining manageable computational complexity through molecular-level descriptions.
Solution Approach 2:
The patent substitutes continuum mechanics with kinetic theory of matter for fluid motion analysis. By treating fluid as a collection of discrete molecules rather than a continuous medium, the model accurately captures jet-effect phenomena, Coanda-effect, and de Laval effect without the limitations of continuum assumptions.
2Ease of manufacture
If conventional jet-effect methods are used, then the implementation is straightforward, but energy conversion efficiency deteriorates
Solution Approach 1:
The patent applies local quality by designing airfoil profiles and nozzle geometries with specific molecular-level characteristics that enhance jet-effect in critical regions. The airfoil shape and surface properties are optimized locally to maximize energy extraction from fluid flow, improving overall energy conversion efficiency.
Solution Approach 2:
The patent introduces dynamic elements including oscillating airfoils and adjustable nozzle geometries that adapt to flow conditions. The airfoil can oscillate to enhance energy extraction, and the system dynamically adjusts parameters to maintain optimal energy conversion efficiency under varying operating conditions.
3Device complexity
If standard airfoil designs are used, then the design process is simple, but jet-effect enhancement deteriorates
Solution Approach 1:
The patent employs asymmetric airfoil profiles specifically designed to enhance jet-effect phenomena. The asymmetric geometry creates favorable pressure distributions and flow patterns that amplify Coanda-effect and de Laval effect, generating stronger jet streams and improving energy extraction while maintaining reasonable design complexity.
Solution Approach 2:
The patent utilizes curved and rounded geometries in airfoil design, including rounded leading edges and curved surfaces that guide fluid flow smoothly. The curvature of the airfoil profile enhances jet-effect by creating favorable flow attachment and reducing turbulence, thereby increasing power output.
4Power
If conventional fluid models are used, then computational requirements are low, but energy harvesting efficiency deteriorates
Solution Approach 1:
The patent segments the fluid domain into discrete molecular entities rather than treating it as a continuous medium. This segmentation approach, based on kinetic theory, enables accurate modeling of energy transfer at the molecular level, improving energy harvesting efficiency while keeping computational requirements manageable through efficient algorithms.
Solution Approach 2:
The patent introduces molecular-level intermediaries that mediate energy transfer between fluid and airfoil. By modeling energy exchange through molecular collisions and interactions rather than continuum heat transfer equations, the system achieves higher energy harvesting efficiency with computationally efficient approaches.
