FOUR VISIONS AS 2020 DRAWS TO A CLOSE
These are four short outlines of the current state of my insights into four subjects that I had researched and first wrote about in 1980 (Patterns in Fluid Flow Paradoxes – Variations on a Theme).
After that book’s publication, I left fluid dynamics research until 2005, when an image on the cover of Physics Today displayed – in vivid colours – a computerized image of organized transverse flow patterns in turbulence in cylinders – patterns that were more accurately predicted in the words on pages 62-63 of my 1980 book.
These are the words:
“While inhibiting longitudinal lamination, this transverse sound energy could permit a form of laminar flow to occur perpendicular to the flow in turbulence. This could permit transverse secondary flows such as those described by Nikuradse in tubes of non-circular cross-section. In cylinders, an axial rotational effect could be permitted with the development of rotating discoid laminations in the plane of the disc-shaped isovelocity profile."
The following works offer insight into fluid laminae, the H20 molecule and transition to turbulence, particularly in water flow.
