Webstricter standard of dynamic similarity exists if the ratios of all forces acting on homologous fluid particles and boundary surfaces in the two systems are constant. Dynamically similar systems are by definition both geometrically and kinemati-cally similar. An important conclusion of fluid mechanics is that in- WebAs discussed previously, most practical fluid mechanics problems are too complex to solve analytically and must be tested by experiment or approximated by computational fluid dynamics (CFD). These data have much more generality if they are expressed in compact, economic non‐dimensional form. portland bds tree reviewIn 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 … See more The Reynolds number and the Womersley number are the only two physical parameters necessary to solve an incompressible fluid flow problem.

"WebJan 24, 2024 · Dynamic Similarity is extremely hard to achieve in some flow conditions, like high-speed aerodynamics where the fluid can no longer be considered incompressible. But even in low-flow conditions it can be difficult to achieve, which is why the topic is complex, and why flow modeling in general is difficult. " - Dynamic similarity in fluid mechanics
