Dynamic Similarity

</dt>
The relationship existing between a model and its prototype when, by virtue of similarity between their geometric dimensions and mass distributions or elastic characteristics, the motion of the model in some respect (such as linear velocity, acceleration, vibration, flutter, etc.) is similar to the motion of the prototype; also, the similarity between the fluid flow about a scale model and its prototype when the flows have the same Reynolds number. </dd>
