WebGeometric similarity. Kinematic similarity. Dynamic similarity. The geometric similarity requires similarity in shape, that is, all length dimensions in the model are λ times shorter than in its prototype. The kinematic similarity implies geometric similarity and indicates in addition a similarity of particle motion between model and prototype. 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. …

"Webkinematic similarity may be too lax a requirement. The stricter 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. " - Dynamic similarity definition

WebThe dynamic viscosity is a constant of proportionality that relates the strain-rate to the viscous stress. Stress has the dimension of force/area, so [T] = ML T2 1 L2 = M LT2: The strain-rate has the dimension of a velocity gradient, or velocity/length, so [D] = L T 1 L = 1 T: Since D has the same dimension as T, we conclude that has the ... WebThis concept is called dynamic similarity and is widely used in experimental aerodynamics to scale up or down a geometry while maintaining the same flow characteristics. Typical examples are scaled-down car models and aircraft models which are used in wind tunnel testing. Passenger aeroplane model in a wind tunnel. Credits: NASA

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 …

WebKinematic similarity: the velocity at any point in the model flow must be proportional by a constant scale factor to the velocity at the homologous point in the prototype flow. (That is, the flow streamlines must have the same shape.) Dynamic similarity: all forces in the model flow must scale by a constant factor to the chrome reachWebDynamic Similarity.
