When full dynamic similarity exists between model and full-scale prototype, their dynamic behavior can be related to each other by simple mathematical conversions.

WebApr 6, 2024 · 7.3.1.3 Dynamic Similarity Dynamic similarity requires that the relevant dimensionless parameters should have the same value for both the model and the prototype. For example, in the simulation of flow through a pipeline, the Reynolds number should be the same for both the model and the prototype. 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 …

The speed of an object is the magnitude of its velocity (the rate of change of its position). A pump is a device used to move fluids, such as liquids, gases or slurries. but and Since where Constant.
WebJun 28, 2016 · The main complication in dynamic similarity assignment is the definition of a acceptance criteria. If the acceptance criteria is such that the response at a certain location does not reach a certain threshold for qualification reason, then a bounding method using only upper bounds may be the best metric.
