In fluid mechanics, dynamic similarity is the phenomenon that when there are two geometrically similar vessels (same shape, different sizes) with the same boundary conditions (e.g., no-slip, center-line velocity) and the same Reynolds and Womersley numbers, then the fluid flows will be identical. This can be seen from inspection of the underlying Navier-Stokes equation, with geometrically similar bodies, equal Reynolds and Womersley Numbers the functions of velocity …

WebSimilarity vs Distance ¶. Similarity vs Distance. Distances such as Euclidean distance or Dynamic Time Warping (DTW) return a value that expresses how far two instances are apart . Such a distance is equal to zero, when the instances are equal, or larger than zero. In certain cases you might need to translate this distance to: WebDynamic similarity implies a correspondence of fluid forces between the empirical artifacts and real-world installations. For orifice flowmeters, the velocity profile and turbulence level of the flow in the laboratory must be similar to the velocity profile and turbulence level of the flow in the field installation.
