Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current simulation tools cannot simultaneously model one-dimensional and multi-dimensional fluid flows within a fluid flow network, requiring separate processing and integration of results, which is inefficient and lacks comprehensive data for complex systems like liquid rocket propulsion and industrial cooling systems.
Innovation Solution
A computer-implemented method that defines one-dimensional and multi-dimensional meshes of nodes and relational data structures to model fluid flow, allowing simultaneous simulation of both types of flows using a single model by integrating flow branches and nodes across the network.

Engineering Contradiction Analysis
1Ease of manufacture
If separate processing of one-dimensional and multi-dimensional equations is used, then processing capability is simplified, but integration efficiency deteriorates
Solution Approach 1:
The patent combines separate one-dimensional and multi-dimensional processing capabilities into a single integrated simulation tool. The system merges different mesh types (one-dimensional and multi-dimensional) and equation solvers into one unified platform, eliminating the need for separate processing steps and manual result integration, thereby improving integration efficiency while maintaining processing capability.
Solution Approach 2:
The simulation tool is designed with multi-functionality to handle both one-dimensional and multi-dimensional flow equations within a single system. It can automatically select and apply appropriate equation types based on the specific problem requirements, providing a universal solution that simplifies the user interface while maintaining specialized processing capabilities for different equation types.
2Measurement precision
If comprehensive data results from both one-dimensional and multi-dimensional equations are obtained, then simulation accuracy is improved, but processing time increases
Solution Approach 1:
The system dynamically selects and applies appropriate equation types (one-dimensional or multi-dimensional) based on the specific characteristics of each component in the fluid network. This dynamic approach allows the simulation to use simplified one-dimensional equations where sufficient and more complex multi-dimensional equations only where necessary, thereby maintaining simulation accuracy while reducing overall processing time.
Solution Approach 2:
The patent applies different levels of computational complexity to different parts of the fluid network based on local requirements. One-dimensional equations are used for components where simplified modeling is adequate, while multi-dimensional equations are applied only to specific components requiring higher accuracy. This localized approach maintains overall simulation accuracy while minimizing processing time by avoiding unnecessary computational complexity throughout the entire system.

AI summary
A computer-implemented method is provided for simultaneous simulation of one-dimensional flow and multi-dimensional flow in a fluid flow network. Processes define meshes of nodes for both one-dimensional and multi-dimensional flow components in a fluid flow network. Another process defines a relational data structure for each adjacent node pair in each multi-dimensional flow component. A flow analysis code is executed to model fluid flow throughout the fluid flow network using the one-dimensional and multi-dimensional meshes of nodes, and each relational data structure.
