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 ... WebIn the attempt to attain dynamic similarity for fluid flow systems, different dimensionless criteria appear according to whether momentum and viscosity, or momentum and gravity, are the dominant ...
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 similarity and dynamic similarity will automatically ensure kinematic similarity. Note: 1.
