Geometric and dynamic similitude
Similitude is a concept applicable to the testing of engineering models. A model is said to have similitude with the real application if the two share geometric similarity, kinematic similarity and dynamic similarity. Similarity and similitude are interchangeable in this context. The term dynamic similitude is … See more Engineering models are used to study complex fluid dynamics problems where calculations and computer simulations aren't reliable.

Similitude is a concept applicable to the testing of engineering models. A model is said to have similitude with the real application if the two share geometric similarity, kinematic similarity and dynamic similarity. Similarity and similitude are interchangeable in this context.

Everest on a topographic map is the same as Mt. Everest itself, only at a much smaller scale (Figures 1a, b, and c). Dimensionless numbers are also useful for scaling …
Websimilitude conditions must be met. The similitude of the geometric configurations is a fundamental requirement, as is the similitude of the angles of attack. Reynolds number and Froude number, as well as Mach number in the case of compressible flow conditions, are pertinent parameters for steady-state (static) or dynamic test conditions. A ... WebFeb 14, 2024 · The prototype–model behaviour similitude requires the equality of all no-dimensional parameters to be obtained from the relevant physical quantities, so in addition to the geometric scale, it is required that the dynamic behaviour in the model follows the same laws that the prototype does (even if somehow simplified).
