Dynamic similarity pdf
WebKinematic similarity occurs when the prototype and model fluid velocity fields have identical streamlines (but scaled velocities). Since the forces affect the fluid motion, geometric similarity and dynamic similarity will automatically ensure kinematic similarity. Note: 1. WebDynamic similarity Dynamic similarity exists when the model and the prototype have the same length scale ratio, time scale ratio, and the force scale (mass scale) ratio. …

Here this term refers to similarity of the forces. It follows, based on Newton's second law, that this requires similarity in the accelerations and masses between the model and prototype. It was shown that the ...
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 …
