Geometric kinematic and dynamic similarity
In fluid mechanics, kinematic similarity is described as “the velocity at any point in the model flow is proportional by a constant scale factor to the velocity at the same point in the prototype flow, while it is maintaining the flow’s streamline shape.” Kinematic Similarity is one of the three essential conditions (Geometric … See more Assume we need to make a scaled up model of coronary artery with kinematic similarity. Reynolds Number, Re = ρvl/μ = vl/ʋ Where, ρ = Density of the fluid (SI units: kg/m ) v = See more • Similitude (model) • Similarity (geometry) • Dynamic similarity (Reynolds and Womersley numbers) See more

WebSince the forces affect the fluid motion, geometric similarity and dynamic similarity will automatically ensure kinematic similarity. Note: 1. When modeling, we need to … 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 often used as a catch-all because it implies tha…

This similarity requires that the length and time scales be similar between the model and the prototype implying that velocities at corresponding points be … WebApr 29, 2024 · The necessity for geometric similarity is the most obvious. Kinematic similarity in fluid mechanics is often referred to as the similarity of streamline patterns. Dynamic similarity requires that forces in full and model scale have the same direction and the ratio of magnitudes full scale to model scale is constant.
WebApr 29, 2024 · The necessity for geometric similarity is the most obvious. Kinematic similarity in fluid mechanics is often referred to as the similarity of streamline patterns. … WebIn 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 ...
