Solution Overview
Problem
Conventional gas-liquid separators are ineffective in microgravity environments and situations with momentum interference, such as on vehicles or aircraft, where gravitational forces are absent or disrupted, leading to inefficient phase separation.
Innovation Solution
A gas-liquid separator design utilizing centrifugal force to direct the fluid mixture through an elongated spiral conduit, where the density difference between gas and liquid components causes centrifugal separation, with a wettable coalescing medium on the outer surface to enhance phase separation, allowing for effective separation without reliance on gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional gas-liquid separators utilize a coalescing medium oriented for gravitational separation, then liquid droplets can migrate downward to a collection point under normal gravity, but the separator becomes ineffective in microgravity environments or situations with momentum interference
Solution Approach 1:
The patent changes the fundamental separation parameter from gravitational force to centrifugal force. The spiral conduit geometry transforms the separation mechanism by inducing rotational flow that generates centrifugal forces, allowing liquid droplets to migrate radially outward instead of downward. This parameter change enables the separator to function effectively in microgravity environments where gravitational separation fails.
Solution Approach 2:
The patent employs a spiral conduit with curved geometry to generate centrifugal separation. The elongated spiral shape creates rotational motion as the gas-liquid mixture flows through it, utilizing curvature to transform linear flow into rotational flow. This curved path design is essential for generating the centrifugal forces needed to separate phases without relying on gravity.
2Productivity
If the coalescing medium is designed for gravitational drainage, then liquid accumulation and droplet growth occur effectively under gravity, but the separator cannot maintain separation performance when gravitational forces are absent or disrupted
Solution Approach 1:
The patent fundamentally changes the driving force parameter from gravitational acceleration to centrifugal acceleration. By designing the coalescing medium to work with centrifugal force rather than gravity, the system maintains high separation efficiency across diverse operational environments including microgravity, vehicular applications, and aircraft where gravitational forces are absent or disrupted.
Solution Approach 2:
The patent creates a universal separator design that functions across multiple environments and applications. The centrifugal separation mechanism combined with the spiral conduit geometry provides multi-functionality, enabling the same device to operate effectively whether on the ground, in microgravity space environments, or in mobile applications with varying momentum conditions.

AI summary
A device for separating gas and liquid from a mixture of gas and liquid phases includes a fluid guide member (14) comprising a fluid inlet and a fluid outlet connected by a conduit (18) configured as an elongated spiral disposed about an axis. A liquid coalescing medium (22) is disposed on an exterior surface of the fluid guide radially outward from the elongated spiral conduit with respect to the axis. The separator also includes a plurality of radial channels (20) providing radial flow paths for fluid from the elongated spiral conduit to the coalescing medium.
