The Dimensional Analysis that we have carried out in this chapter clearly indicates that to achieve dynamic similarity the all the non-dimensional …

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 … Webobjects are geometrically similar and that the flows around them are dynamically similar. Dynamic similarity is achieved if the characteristic flow velocities U p and U m are such …

WebApr 6, 2024 · 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. Mathematically, for flow through pipes, the dynamic similarity … Webobjects are geometrically similar and that the flows around them are dynamically similar. Dynamic similarity is achieved if the characteristic flow velocities U p and U m are such that the forces at all homologous points—such as the two marked by asterisks—are proportionate.
