Scale effects and full-scale ship hydrodynamics: A review

Scaling problems in ship design refer to the difficulties of translating performance data from a small-scale model to a full-scale ship, as physical forces like viscosity and wave drag do not scale proportionally with size.

Crypto space here? Trading strategies that work in niche mkts or early on, may not work when they are larger /more mature etc.

Henry Gifford writes:

The problems with water include the size of water droplets – they won’t form larger than a certain size – and Reynolds Number, which has to do with viscosity (mentioned below), and how to calculate it. Basically, a certain flow velocity in a small pipe (or river) will be turbulent, while in a larger pipe it might not.

Movies that use models of ships to show dramatic events with ships always show water droplets that are way, way too large, making it obvious to those who notice that they are looking at a model.

Nils Poertner responds:

Makes a lot of sense, Henry, thanks! (Equity sell-side analysts love to scale things (to the point it makes no sense anymore). Wile E. Coyote moment for NVDA et al coming soon perhaps.

Stefan Jovanovich predicts:

Grok - our FO's new member (he/she/it works for free like Harry Potter's Dobby) - thinks the moment will be 2031-32. [Click on chart at right.] We take the current AI events as a direct comparison to the creation of U.S. Steel.
