Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Equipment with gaseous fuel-consuming engines can be damaged by two-phase or multiphase flow from fuel sources, which existing systems fail to effectively detect and prevent, leading to potential engine damage.
Innovation Solution
A system comprising a flow measurement device, such as a coriolis flow meter, and a shutdown device, controlled by a computing device that measures properties like drive gain, fluid density, and mass flow rate, and stops fuel flow when pre-set limits are exceeded, preventing two-phase or multiphase flow from reaching the engine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing systems are used without detection devices, then the system is simple and easy to operate, but the engine is vulnerable to damage from two-phase or multiphase flow
Solution Approach 1:
The flow measurement device is positioned upstream in the fuel flow path to detect two-phase or multiphase flow conditions before they reach the engine. The system performs preliminary detection and triggers shutdown action in advance, preventing liquid fuel from entering the engine and causing damage.
Solution Approach 2:
A flow measurement device acts as an intermediary between the fuel source and the engine. This intermediary device monitors fuel flow properties and provides early warning of two-phase flow conditions, enabling protective shutdown before the harmful flow reaches the engine.
2Reliability
If detection systems are added to detect two-phase flow, then engine protection is improved, but the device complexity and measurement requirements increase
Solution Approach 1:
The system replaces complex mechanical detection methods with a flow measurement device that uses electrical or electronic sensing principles. The device measures flow properties such as density or velocity changes to detect two-phase flow, providing accurate detection with simpler measurement mechanisms.
Solution Approach 2:
The flow measurement device detects two-phase flow by monitoring changes in flow parameters such as density, velocity, or mass flow rate. When liquid enters the gas stream, these parameters change in characteristic ways that the device can identify, enabling accurate detection through parameter analysis.

Effectively detects and prevents two-phase or multiphase flow, thereby protecting engines from damage by ensuring fuel flow integrity and preventing liquids from reaching gaseous fuel-consuming equipment.
Implementation Method 1
A flow measurement device, such as a coriolis flow meter, can be positioned in a flow path between a fuel source and an engine. The flow measurement device can measure various properties of the fuel flow travelling through the flow path, for example the drive gain, the fluid density, and the mass flow rate of the fuel flow.

AI summary
A system can include a flow measurement device positionable in a flow path for measuring a property of the fuel flowing through the flow path and a shutdown device positionable in the flow path for controlling the fuel flow through the flow path. The system can also include a computing device that is communicatively coupled to the flow measurement device for receiving the fuel flow property and from which the presence of two-phase flow or multiphase flow can be detected. The computing device is also communicatively coupled to the shutdown device for controlling fuel flow through the flow path in response to the detection of two-phase flow or multiphase flow.
