Are Reynolds Vortices a Real Scientific Phenomenon?

Click For Summary

Discussion Overview

The discussion centers around the concept of Reynolds Vortices, as mentioned in a fictional book. Participants explore whether these vortices are a recognized scientific phenomenon or a fabrication by the author for narrative purposes. The conversation touches on fluid mechanics, literary interpretations, and the blending of scientific terminology in fiction.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • stockzahn inquires about the existence of Reynolds Vortices, noting a lack of information found online.
  • One participant expresses unfamiliarity with the concept, suggesting it may not be well-known in fluid mechanics.
  • Another participant discusses the literary use of scientific terms, suggesting that the term "Reynolds Vortex" may be a creative invention rather than a scientific one.
  • stockzahn later shares that the author confirmed the vortices were made up for the story, indicating a lack of scientific basis.
  • There is a mention of von Karman vortex streets as a potential related concept, though it is not confirmed as equivalent to Reynolds Vortices.

Areas of Agreement / Disagreement

Participants generally agree that Reynolds Vortices do not appear to be a recognized scientific phenomenon, with some expressing uncertainty about the term's validity. The discussion remains unresolved regarding the implications of blending scientific concepts with fiction.

Contextual Notes

The discussion highlights the potential for confusion when scientific terms are used in literary contexts, and the limitations of understanding based solely on fictional representations.

Dear all,

recently I read in a belletristic book about Reynolds Vortices. In the fictitious story the author writes about special (Reynolds) vortices generated in the whitewater, which can be passed in only one direction by objects of a "critical" density, which then will be kept in the vortex as long as it exists. Objects with densities deviating from this density can leave it (again).

I've never heard about this phenomenon until then and also after a quick search in the internet I couldn't find any information about these vortices. Does anybody know about these Reynolds vortices (maybe there is a different name) or is it just made up by the author in his story?

Thanks in advance,
stockzahn

I can honestly say I've never heard of the concept over the course of my adventures in fluid mechanics. That doesn't mean it doesn't exist, but it's certainly not a very well-known phenomenon if it does.

Literature requires different analytical tools from technical documents. While not familiar with this author, "whitewater" invokes both beauty and dynamism typical to belle lettres stories. The reader (or characters, the post is limited) exist poised at the interface of water and atmosphere presumably at the surface.

Reynolds (number) is a convenient indicator of smooth, potentially guiding fluid flow, becoming turbulent "whitewater", thus a dimensionless symbol of movement, change. The vortices could refer to von Karman vortex streets that represent difficulties or obstructions that arise in the flow as the plot progresses. "Critical density" could refer to knowledge and reasoning overcoming perceived obstacles (vortices) to smooth flow. I'd need to read the book for further analysis.

Generally, writers like to borrow terms and names from physics then concatenate them for literary effect. Einstein intersection (Chip Delaney), Von Neumann machines (Arthur Clark), and now Reynolds vortex (uncited).

Thank you very much for your responses. Since nobody seemed to know about Reynolds Vortices, I wrote an e-mail to the author of the book and he, quite surprisingly, promptly replied. He admitted that he made up this kind of vortices he "needed" for his story.

@Klystron: For sake of completeness of your list: Reynolds Vortex (Joerg Maurer).

To get really known as a scientist, you need to have cool sci-fi stuff named after you, not just some number.

Thanks for the information. It seems as if the author succeeded as a writer in that you were motivated to ask the question. I chose von Karman vortices as an example in part because of the beauty in their representation on screen. Unlike the classical whirlpool representation "Scylla and Charybdis" from Homer's Odyssey, a vortex street appears in a fluid when physical conditions lead to that formation not only above rock formations as in the Straits of Messina.
