Dynamic similarity pdf
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.

Fundamental to concept of similarity and model testing Enables scaling for different physical dimensions and fluid properties 1.3 Physical significance of non-dimensional groups The main components of force which may act on a fluid element are those due to viscosity, gravity, pressure, surface tension and elasticity.
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 ...

Here this term refers to similarity of the forces. It follows, based on Newton's second law, that this requires similarity in the accelerations and masses between the model and prototype. It was shown that the ...
WebKinematic similarity occurs when the prototype and model fluid velocity fields have identical streamlines (but scaled velocities). Since the forces affect the fluid motion, geometric …
