Definitions
- Swirl flow has a number of advantages over conventional flow. Pressure losses (and energy losses) through turbulence can be reduced. In addition, the velocity profile of the flow across the pipe is more uniform (or blunter) than it would be with conventional flow. As a result, fluid flowing in a swirl flow tends to act as a plunger, removing sediment or debris which may have accumulated on the pipe walls, which is of particular importance in hydroelectric plant.
- the flexible straight member is a second flexible tubing portion.
- Such a method produces two helical portions simultaneously, which can then be separated to provide two separate helical portions. Further, the two helical portions are wrapped around each other, and are thus in intimate contact, which may be advantageous in various situations .
- Figures 3a and 3b illustrate a first method of manufacture of a helical pipe
- a particularly preferred method of forming a helical portion involves the use of a helical mandrel, and is illustrated in Figures 5a to 5e.
- a continuous length of flexible pipe can be drawn through a comparatively short length of mandrel, and can be treated to retain its shape as it is drawn through (for example, by heating a pipe formed from a thermosetting resin) .
- the more uniform velocity profile which can be achieved with swirl flow also confers a number of advantages.
- the flow rate near the wall of the pipe is larger than it is in conventional flow with straight pipes, and so there is less risk of solid material in the pipe being deposited on the wall of the pipe. This is of particular importance if the piping is used to transport slurries or the like.
- Another advantage of the secondary motion and mixing associated with swirling flow in a helix is inhibition of the development of flow instability and turbulence; this has been shown experimentally.
- a further advantage of the more uniform velocity profile is that it reduces axial dispersion and consequent mixing if the same piping is used to transport different materials. This can occur, for example, when a reactor is being filled with ingredients during batch processing.
